Data taken at CIT
These are Ascii data files ~8MB which can be saved to your local disk.
The format is x,y,z the position units are millimeters and the height units are waves (1064 nm).
For each pixel with a null value the ascii set BAD is entered (this is a headache!) However there are no nulls on the inside of the map.  This map covers the central 150 mm of the 250 mm part.

 Wavelength      1064
 Pixel array is 576 x 480
 Pixel size  0.2668
 Aspect  Ratio 1.167000 = y/x
There is a 12 line header at the beginning of each file


Data taken at CSIRO
The following are Ascii data files ~9MB which you can save to your local disk.

The format is x,y,z the position units are millimeters and the height units are waves (690.7 nm).  For each pixel with a null value the ascii set BAD is entered (this is a headache!) However there are no nulls on the inside of the map.  This map covers the central 240 mm of the 250 mm part.
