  ETMX  (2'x4',  4" thick, 32.75" high) (just east of east end) - East arm transmitted, initial pointing
  ETMY  (2'x4',  4" thick, 32.75" high) (just south of south end) - South arm transmitted
  OPLEV (2'x4',  4" thick, 32.75" high) (just north of vertex) - optical levers for vertex suspensions
  AP2   (3'x4', 12" thick, 32.75" high) (just west of vertex) - OMC transmitted, and beam output mirrors
  BSPO  (3'x5', 12" thick, 31.25" high) (just south of vertex) - BS pickoff beam
  ITMXY (3'x5', 12" thick, 32.75" high) (just east of vertex) - ITMX, ITMY pickoff beams
  AP1   (4'x6', 12" thick, 32.75" high) (south of PSL and SP&MC tables) - 
  SP&MC (5'x12', 24" thick, 32.75" high) (just south of PSL table)
  PSL   (5'x10', 12" thick, 25" high) 

All beams are nominally 36.75" from the floor,
except for the ones on the PSL table.

All ISC table tops are nominally 32.75" from the floor,
EXCEPT for the BSPO table, which must fit below
the MC beam tube.
Beam height is 4" from table top.

PSL table top is 25" from floor,
beam height is 3" from table top.
A periscope will bring the beam from 
25+3" to 36.75".

Vacuum chamber tables are nominally 31.25" from the floor,
beam height is 5.5" from table top.
