The Project Control Meeting
Agenda for Monday October 5, 1998 will be:
(Meeting time: 10:30 am Pacific Time)
http://www.ligo.caltech.edu/~sanders/Hanford_Operational_Procedures/
The revised procedures pertain to venting a 2 kilometer beam tube module and the training certificate for each employee or working visitor. These can be found at:

LIGO Hanford Observatory (LHO) Operations (F. Raab)
=========================================================
General Items:
--------------
The PSL laser has been shut down following an incident where the 10-W
beam escaped the laser-table enclosure. The PSL team works
within a secondary, movable safety enclosure that surrounds the laser
table and work area (about a 24-ft square work area), so there was
never any danger to other workers in the LVEA from the incident.
Members of the PSL team inside the secondary enclosure were eye safe
with their goggles on, and no one was contacted by the beam. But we
now
have some serious burns in a computer monitor to underscore the need
for vigilance in working with this powerful laser source.
An analysis of this incident and an explanation of the need for prompt
notification when similar incidents occur was the topic of the weekly
Business & Safety Meeting at LHO on 9/29, which included participants
from Pasadena (via conference phone) .Steps to improve the safety
of laser operations were discussed and Peter King and Doug Cook were
tasked with drafting a revised Standard Operating Procedure for the
PSL
operation in the LVEA. It is hoped that this work can be concluded
and
laser operation resumed by the week of October 5.
Seismic Isolation Installation:
-------------------------------
(C. Gray & H. Radkins)
Completed the surveying task for locating the Grout Plates for the
Optical Levers in the LVEA. Still need final approval on the positions,
then we can mark and drill holes, and finally, locate the Grout Plates.
Protection for the Bellows is on the table with comments incoming for
decision 10-1.
HAM--All 2K Piers have been torqued down and the grouting was scheduled
to start 9-29 but should go 10-1. Apollo has completed the floor
roughing on the 4K pier so now Piers can be installed.
BSC--All the BSC Pier locations (Anchor Bolts) have been marked in the
LVEA! We need to make check measurements on a few still. The
first
Piers were located on the anchor bolts late 9-30!
BSC 1st-Article Test:
---------------------
(H. Radkins)
Actuation(HYTEC)--Motion has been going on for a couple weeks now.
Position monitoring is in progress. Complicated motion (multi axis)
is
soon to follow. Next week: Fine-x motion!
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, F. Raab and W. Althouse)
VAT Technicians were out here last week to adjust the 10" valves on
the
ports for the 3 remaining modules at Hanford (Y1, X1, X2). Adjustments
were completed and leak checking of valve bonnets seals is proceding.
The Bake Out has continued with some minor problems. PS2 (DC power
supply) breaker tripped Sunday (9/20/98). We investigated the possible
causes and have been unable to determine a specific cause (we are
continuing to monitor this very closely). We are also investigating
possible replacements, refurbishment or bypassing of these breakers
to
preclude any further problems. The Cryopumps are working and there
have
been a couple of temperature transients, we are investigating these
to
try and determine what could be the cause.
The required outgassing target for water has been achieved and the
hydrocarbon outgassing appears to confirm that we have a clean module.
We have therefore begun reducing the Y-2 module temperature. This is
being done in steps to diagnose the source(s) and strength(s) of
hydrogen seen in the beam tube.
We are working on a layout for the additional office needs that will
be
required once detector installation starts. We are getting quotes for
the
furnishings from several suppliers.
We are also getting quotes for additional landscaping at the site. We
hope
to have some sketches and cost quotes soon that we can discuss with
LIGO
management.
We received a quote from Aetna Insurance for health insurance at the
site.
This has been passed on to Liz Wood for evaluation by Caltech HR.
Several safety issues were addressed: 5 MPH speed limit signs were
installed in all areas that forklifts will be
operated, and a first draft of the LLO Accident and incident investigation
report was created. Modified generic forklift "pre-operation" checklist
for
our needs. Each forklift will have its own checklist aboard.
We have scheduled our first outreach participation in "Family Science
Nights" with three minority elementary schools in East Baton Rouge
Parish
later this year. We have been working through Mignon Morgan, who is
the NSF
Program Coordinator for science education in the EBR schools and is
a
former participant in Caltech's CAPSI program.

Date: Wed, 30 Sep 1998 07:48:28 -0700
From: Larry Jones <jones_l@ligo.caltech.edu>
a. Livingston Installation
CBI performed the Y Arm preview accum on 9/23 and
Shaw's
first cut check of air signature taking AMUs 32
& 40
directly is 8E-7 & 5E-7 tl/s--an encouraging
level at
1000 hr pumping, for the whole arm.
CBI's data collection equipment was again damaged
by
lightning, losing a circuit board and a computer.
Shaw has proposed that temperature and pressure
monitoring
only take place during accumulations, and that the
system
be disconnected from the tube at all other times
to
minimize future damage. A compromise is being considered.
Worden has requested one of the roughing carts used
by CBI
to be shipped to Hanford for use in pumping down
modules
prior to bake. CBI and Sibley have agreed, and Franklin
is taking care of crating and shipping the unit.
b. Other Issues: VAT Valve Adjustments
VAT valve adjustments at Hanford are complete; Hanford
personnel are performing leak checks.
No report received on civil construction.
Date: Thu, 01 Oct 1998 20:22:00 -0400
From: David Shoemaker <dhs@ligo.mit.edu>
----------------------------------------------------
DETECTOR GROUP -- Whitcomb/Shoemaker
(WBS 1.2, 1.3)
----------------------------------------------------
No report this week.
----------------------------------------------
Interferometer Sensing and Control -- M Zucker
(WBS 1.2.1.1.6, 1.2.1.1.7)
----------------------------------------------
ASC fabrication (Smith)
----------------------
Finished the drawings of the wedges for the Optical Levers to the 2K
Beam Splitter and Recycling Mirror(WBSC4 and WHAM9). They will
be
sent out for quotes this week. Started the drawings for the wedges
to
the 2K ITM in BSC 7 and 8.
We have received a large quantity of the parts needed for IOT7.
The
remaining items are from Laser Metrics-a Q-switch due Oct 18, Karl
Lambrecht-a Polarizer due Oct 18, and the enclosure due Oct 23 .
Myron is just about finished with preparing the Optics Lab and has
started kitting the parts, getting them clean and ready for assembly.
We will start IOT7 assembly early next week.
ASC initial alignment fab (K. Mason)
------------------------------------
Doing design and calculations for
IAS theodolite platform and tooling. All theodolite/autocollimator
adapters and fixtures are now out for fabrication.
LSC lock acquisition (Ware)
----------------------------
No report.
LSC supervisory control (P. Fritschel, E. Daw)
-----------------------------------------------
o Following last week's ISC meeting in Hanford, Ed & Peter have
begun
to look more carefully at the functions & requirements of the ISC
'Master CPU' -- this is the processor(s) that will interface the
DAQ/GDS data to/from the ISC servo processors, run EPICS, provide
network communications, etc.
-------------------------------------------
Lasers and Optics -- J. Camp
(1.2.1.1.2, 1.2.1.1.3, 1.2.1.1.4,1.2.1.1.5)
--------------------------------------------
Prestabilized Laser -- Peter King
--------------------------------------------
- Installation of the 2k IFO PSL was not completed during the allotted
3
week time period. A number of problems arose during the installation
phase, ranging from insufficient supplies being shipped to the site
and an
over-estimation of the facilities available. Whilst consideration
was
given to the equipment needed to install the PSL, the PSL was not
self-sufficient in equipment needs.
The experience gained will come in handy for the
next installation
period and for subsequent installation at Livingston and Hanford.
- A safety related incident, in which the
main laser output went beyond the
confines of the optical table enclosure, has lead to a review of the
temporary standard operating procedure and current beam handling practices.
The incident occurred when an attenuator was being installed in the
main
beam of the laser. The beam dump installed was not large enough
to contain
the dumped beam. The stray beam hit a computer monitor located
at the edge
of the IOO/PSL optical table.
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
Installation:
Sany has just returned from Hanford; Qi-Ze will be heading out next week.
Cleaning of the in vacuum non-suspended optics for the 2 km IOO has
commenced. Removing the surface contamination layer has proven
difficult;
in fact, we have not been able to satisfactorily clean any of the mirrors.
The reasons for this is under investigation. We are
doing further investigations to assess the condition of all of the
optics.
An SOS test stand has been set and is fully functioning; the dummy 3"
optic has been successfully balanced and damped using the first article
SOS electronics.
Sany, Hai Sheng, and Dave hung a test 3 inch optic in an SOS tower.
After
balancing the optic and gluing the wire standoff, we activated the
magnet
actuators. We first used a molybdenum wire to hang this optic. (The
wrong
wire was sent by Cal. Fine Wire) We measured the photodetector signal
of
actuators using an audio spectrum analyzer. Peaks were observed at
1.69
Hz, 18.9 Hz, 27.7 Hz, 28.9 Hz, 34.9 Hz and 37.8 Hz. Among these peaks,
the
one at 18.9 Hz was very sensitive to the orientation of the actuator
around the axis along the magnet. When the actuator is oriented at
a
certain direction, this peak was hardly seen.
We replaced the molybdenum wire with (the correct) steel wire and made
the
same spectrum measurement. This time, peaks appeared at 1.63 Hz, 14.5
Hz
(only in the lower right and upper right actuators), 21.18 Hz, 29.3
Hz and
38.3 Hz. Among these peaks, the one at 21.18 Hz was sensitive to the
orientation of the actuator. The peaks appear sharper in the case of
the
steel wire than the molybdenum wire.
The final batch of 2 km IOO in-vacuum components has been sent to Caltech
for baking.
Mode Matching Measurement:
Bullseye: Pre-mode cleaner is locked to the laser in high finesse mode.
The output mode seems satifactorily round. Currently Qi-ze is
struggling to align the laser to the reference cavity and matching
the
TEM00 resonant frequency for both cavities.
Procurement:
The mode cleaner curved mirrors are being reworked by GO. They
should be
ready next week for re-coating.
The periscope have been received at the site; they will need to be cleaned
before being put on the PSL table
Four MMT3 mirrors have now been received by UF; waiting on radii of
curvature measurements.
Mechanical Design and Machining:
PSL beam tubes and holders ready to go.
High Power Measurements:
No significant activity to report.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
The IR interferometer arrived Friday. Acceptance testing took
place
Saturday and Sunday. The instrument showed good repeatability
during quiet
times, these quiet times come and go even on a Saturday evening.
The
interferometer was found to have changed alignment in shipping, we
think
due to the fact that a pellicle was removed for protection of the optic
during shipping. The subsequent replacement of the part was not
exact.
A representative from Veeco is coming out Sunday morning the 4th of
October
to realign the system. An acceptance test is scheduled for Monday.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
REO Contract - COC's coatings: Received two 2ITM's from REO. They do
not
show cleaning problems. We are in the process of evaluating how the
imperfections on the surface (coming from polishing or coating) relate
to
scatter.
Also, we would implement a quick QA coating procedure suggested by
the
Florida's group and proven very useful, where the mirrors are looked
at with
a YAG laser to observe scatter.
We are working a schedule that would allow me to be present at REO
during
all future COC's coatings.
We are supporting the group from Florida by inspecting their 2" mirrors
after coating, and evaluating their cleaning techniques.
Core Optics Support -- Michael Smith
------------------------------------
BEAM-DUMPS:
Ara has redesigned the vertical support structure for the generic
beam-dump. M Smith is re-calculating the expected resonant frequencies
before releasing the drawings to the shop for the prototype modification.
ITM BAFFLES:
A. Rosa has moved the ITM-Lx baffle slightly so that the spot reflected
onto the wall of the spool piece from the 2K ETM beam during lock
acquisition can be viewed through a pump-out port in the WBE-5 spool.
Moving the baffle required repositioning the support structures for
the
glass frame and relocating the optical lever beam holes in the baffle.
The
redesign was completed for the ITM-Lx baffle. The redesigned baffle
works
okay in the mid and end station positions ETM-Lm, ETM-Le; and the reflected
beam spot can be viewed through one of the horizontal optical ports
in the
spool piece. The ITM-Ly baffle design will be different from the ITM-Lx
because the pump out port in the WBE-6 spool is a miror image of the
WBE-5
port.
A unique baffle ETM-Rm is required at the far (right) side of the mid
station BSC facing toward the 4K ETM. This large baffle must be mounted
inside the BSC, and the reflected beam spot of the 4K IFO onto the
walls of
the BSC during lock acquisition must be viewable from an appropriate
port
in the mid station BSC chamber.
ETM and PO Telescope-
A preliminary design review for the mechanical design of the PO telescope
was held by CC Development at CIT on Friday 9/25/98. A final design
review
will be held on 10/2/98 at CIT. A preliminary design review of the
ETM
telescope will be held on 10/2/98 at CIT.
The optical design of the ETM telescope was changed to incorporate a
less-troublesome SF6 glass for the smallest eyepiece lens. Optics 1
will
discuss the preliminary results of the mechanical tolerance analysis
of the PO and ETM telescopes on 10/2/98.
FARADAY ISOLATOR SYSTEM
A specification has been completed for the Faraday Isolator Assembly.
A
quotation is expected from the vendor. Irena is preparing a sole-source
procurement package.
COS VIEWPORTS
The specification for the COS Viewports has been revised to incorporate
appropriate QA/QC wording and submitted to Irena for preparation of
a
sole-source procurement package. A quotation is expected from the vendor.
ALIGNMENT SYSTEM
The alignment telescope was mounted using a tilt/yaw mounting bracket
onto
the Velmex two-axis positioning apparatus. The alignment beam short-term
pointing reproducibility was tested to be < 10 arcsec, and the pointing
resolution approx 1 arcsec.
MOCK-UP
The three PO telescope mockups have been placed on the HAM mock-up
facility. A mounting structure for the BSC SEI table is being constructed.
An outside table is being set up for placing the alignment telescope,
from
which a simulated alignment beam will be projected onto a simulated
pick-off mirror on the BSC table and beamed down to the PO telescope
on the
HAM table. The proposed elevation, pitch, and yaw alignment procedure
for
the PO telescope will be evaluated.

Isolation Group -- M. Fine
--------------------------
Seismic Design (Mike Fine)
--------------------------------------
1. Rack Assembly/Checkout:
Hytec completed the conversion of the limit switch signals to 24 volts.
The
junction box was installed and tested. They did locate one faulty
limit
switch
during these tests, but have already received a replacement from Daedal.
They
will be installing this switch early next week.
2. BSC Coarse Actuator Test:
Hytec drove the system in the W direction last week and experienced
under
voltage and motor faults on one of the W axes. They still need
to identify
the
source of these faults. More data is needed before any conclusions
are
possible.
3. Air Bearing Testing:
Hytec is continuing the air bearing testing. They have received
the flowmeter
and have installed it into the system. They have identified a
discrepancy
between
the flow measurements of Specialty Components and Hytec, and are currently
trying to identify and correct any errors. This should be completed
sometime
this week.
4. Fine Actuator Test:
The tests are planned to start around October 8. Besides overall
system
functionality, the bulk of the testing envisioned at this point will
look at
synchronization issues between the 4 PZT drives and the effect on possible
U to yaw (Rz) coupling, the static range and frequency response, and
the
impact
of coarse actuation motion on PZT external preload.
5. WHAM7 Hardware:
Allied shipped 1 complete set of HAM hardware to Hanford this Wed and
expects
arrival on Friday. 4 scissors tables, alignment pins, and 16 x-y translation
plates will be shipped out of Los Alamos on 10/6, expecting arrival
at LHO
on 10/13. 4 airbearings from Specialty Components have arrived at Hanford
this week.
Suspension -- (Janeen Hazel/Mark Barton/Mike Fine)
-------------------------------------------------------------------
1. LOS Welded Structure:
Brookfield delivered the last five LOS1 height adpaters yesterday.
Janeen
will
be visiting Brookfield next week to inspect their first structure with
welded
brackets that have cleaning slots.
2. Alignment Fixtures:
Superior Jig will deliver first two sets of fixtures early next week.
The support beam will be a week later due to changes we initiated
at the piece part level.

---------------------------------------------------------
Global Diagnostics System (Daniel Sigg)
--------------------------------------
No report.
Physics Environment Monitor (Alex Marin)
-------------------------------------------
Most of the work was done on Wilcoxon accelerometers
evaluation. Results will be given soon.
Optical Contamination (Daqun Li)
--------------------------------
The approved vac-seal and viton have been removed from cavities 1
and 2, which are now loaded with teflon wires soldered with connectors
and air baked metal parts (aluminum and steel). Cavity 2 containing
the metal parts has been relocked while cavity 1 is still pumping.
The previous noisy ringdown detector for cavity 3 (empty) has been
replaced with a quieter one and data taking is going on with the new
detector. This replacement will help judge whether the previously
observed instable ringdown data were due to a noisy detector or not.
The communication problem between the stepper motor controller and the
PC has been solved. Automation programming for the Loss Scanner
is
currently going.

A purchase order in the amount of $4,000 was issued to Professor Philip Krider of the University of Arizona for a report detailing the results of an audit performed at both sites concerning lightning protection.
A consulting contract was issued to Ms. Florence Kaufman to perform continuing accounting services for LIGO in connection with resolving encumbrance issues.
The contract with DEMCO to provide electric power to Livingston was increased by $371,000. This amount was approved by the CCB to cover the remainder of FY98 and half of FY99 with construction funds.
[The following summary of efforts to date was provided by Kay Hattori.]
Activity completed to date:
The list of large contract accounts provided by LIGO has been completely reviewed and incorrect posting of expenses have been removed from the beginning balances and journaled to specific contractor Purchase Orders to properly reflect expenditures and uncommitted funds on a line item basis.
Amounts in excess of $25K in 3220 accounts (for the first $25K of subcontracts) have been identified and corrected.
A recommendation was made to LIGO to attach an instruction form to invoices which have retention to make sure that Accounts Payable has all the information that they require.
A recommendation was made to Purchasing to create a more "user friendly" form for managers to fill out to facilitate re-allocation of encumbrance amounts.
Petty cash charges to the 2010 account for Supplies and Expenses have been identified for LIGO to facilitate follow-up.
LIGO Accounts Payable staff have been provided with a binder containing all of the reconciling adjusting journal entries that were made during the period of June through August 1998.

1.4.3.3 Modeling & Data Analysis (KB/HY/AL)
e2e modeling :
multi-mode :
Several validation testings for the multi-mode implementation
have been performed. Comparison with 40m FP results was successfully
completed. It shows that Guoy phase calculations are being properly
done and related data is being passed correctly among various elements.
Evolution of fields due to changing pitch and/or yaw in mirrors of
3-Km
Virgo and 4-Km LIGO FP cavity was also studied. Results tallied quite
well with other codes. The new multi-mode versions of propagater and
mirror and other optical components like modulator, demodulator,
power-meter etc seem to be interacting quite well with each other and
with good accuracy.
mechanics :
A new data type clamp_data has been introduced, with a few new and
modified modules so that Adlib modules and mechanics modules can
communicate. The mechancis part of the code has been modified to use
the
new data type. An example using the new data type will be sent to Cella
with examples.
Data Analysis Group:
Philip Ehrens:
* Specified user functions implemented in TCL layer of the
generic API.
* extended and isolated TCL function set for generic API.
Dave Farnham:
* Wrote specification for the extended Tcl commands which are exposed
by the C++ layer in the genericAPI.
* Added support for n-dimensional arrays, XML comments, and 'container'
elements to the LDAS internal light-weight format needed in
the
genericAPI.
* Added support for sending arbitrary tags through sockets to the
genericAPI.
Stuart Anderson:
Fiber optic cable has been run on the 6'th floor of Millikan to reistablish
a high speed ATM connection to the HPSS tape robot system. The network
configuration has been upgraded from allowing just a single LIGO workstation
connection to now allow any LIGO workstation with a direct connection
to the LIGO ATM switch to connect through the CACR ATM switch
to either HPSS or a few of the ATM capable CACR parallel computers.
Kent Blackburn:
Spent most of the week reviewing applications for software engineering
positions and carrying out the follow-up interviews and reference checks.
So far I have contacted 4 individuals and have 2 more to consider for
LDAS software development.
Met with Phil and Dave to hash out the names, parameters and return
types
for extended TCL commands written in C++ to provide socket communications,
store/restore, logging, help and other functions for the genericAPI.
The
specifications for these will be recorded in a "genericAPI base
specification or implementation" documented.
Met with Albert on two occasions to discussion revisions and improvements
to the LDAS software and hardware schedules. These were then made into
transparencies just in case it was requested in the Syetems Integration
meeting on Thursday.
Spent sometime over the weekend learning how to use a Jazz drive and
an
associated parallel port to scsi adapter for the purpose of backing
up
LIGO PC based laptops. I was not able to get winzip or the window98
backup
utilities to work with this device so I used fastZip which doesn't
make a
full backup, only copying non-empty folders. At the very least having
this level of backup will simplify the recovery of a disk failure,
but it
is not as great a solution has I had hoped.
Bruce Sears:
* continuing work on porting bakeout tcl application to tclet and
interfacing it with the bakeout database service.
Walid Majid:
I am preparing a note, summarizing the results of my studies of galactic
matter distribution in nearby sky. I have mainly focused on the
Tully
catalogue of nearby galaxies, which extends to about 50 Mpc.
I have also been working on a module that translates Frames into XML
(LIGO's light weight data format), not including the actual data
encapsulated in a Frame. This would serve as some sort of a table
of
content for Frames. Using a Javascript I can already create a
tree
diagram of the contents of any given Frame and display it on a browser.

users. Includes setups at Bridge, Lauritsen and Millikan. Hopefully,
the moving
and new setups will taper down these have taken up a great deal of
time the past
few months.
3. Began getting the new color printer in Millikan installed.
4. Worked on multiple procurement issues. Mainly, getting the new servers
in.
Also, getting new quotes for computers, tape robot units, network equipment
and
software upgrades.
5. Samantha made multiple corrections to the IP tables being used for
documentation.
6. Installed more cables for the networks as well as the small network
hubs at
multiple locations.
7. Spent a good deal of time keeping the e-mail going. There are bursts
of 70+
messages sent within a 1-5 minute period which causes the mail relay
host to
generate too many mail daemons. The unit has to be rebooted to get
everything
cleared out. It can be cleared out manually but this usually generates
multiple
copies of the same message to be sent.
We are working on some procedures to keep closer tabs on this issue
until the
new servers arrive. Hopefully, they will handle the e-mail load better.
Also, it
will give us the chance to rework the configuration files.
8. Working on procurements for Livingston and going over items with
Hanford.
This is also part of getting the GC financial documentation updated.
9. We were able to confirm that the addresses we currently have for
the T1
connection at Hanford are temporary. However, doing more detailed testing
for
the e-mail setup and other items will be worked on.
Arranged and processed the paper work for 23 new trips to various locations. Assisted some Oversight Committee members with travel and/or information regarding their meeting in Hanford on October 29th. Several of the 23 trips arranged this week were for the NSF Review in Hanford, WA. Hotel reservations (I have a block of 40 rooms at the Shilo Inn at $45.25 per night) and 6 van rentals have been arranged for. Once again as soon as I know who will be attending the meetings I will ask for volunteer van drivers.
Worked on the ever present backlog of Expense Reports and completed 17 reports. I had hoped for more but several of these 17 were for foreign travel and they consume a considerable amount of time due to translating receipts and determining exchange rates then computing the traveler's charges using these exchange rates.
Performed miscellaneous duties as requested by various members of the LIGO Project here at Caltech, as well as for members of the staffs of each of the two (2) sites.
Prepared and distributed the Weekly Travel/Vacation Itinerary Report for LIGO Staff and Visitors.
Processed Staff Payroll, incorporating various
recent changes, new hires, terminations and the processing of Vacation/Sick
Leave accounting.

After receiving a message from the keepers of the Caltech Personnel Directory giving me an extremely short deadline and upon realizing that a substantial portion of LIGO’s employees were not in the phone book, I set out the word to everyone to fill out P-53 forms. At last count, I had received 37 changes. Even the LIGOites at the sites should fill out P-53 forms. Yes, they can and should be in the Caltech Personnel Directory. They are Caltech employees, too.
Typed up changes on PAN forms so employees at the sites can have their paychecks and check receipts mailed to them directly from payroll rather than going through us here first.
Dealt with the usual personnel issues.
Dorothy Lloyd
Continued processing heavy load of purchase requisitions, POs, change orders, check request, etc. as well as an extremely heavy load of invoices.
Followed up and tracked problems with invoice payments.
More help arrived on Monday and I focused much of my time training this person as well as support my other helper. [At last -- I can see a little light showing at the end of the tunnel...thank you LIGO!]
