Art & Tom,

here's our measurements of the A4 coil with the laser tracker.  The data is 
taken on the A-side septum, between clamps 60-65 and 80-95.  The data is in 
the Verisurf inspection report format.  The points were taken using the 
standard pattern that we employ during the Romer arm measurements (3 
columns of 11 points between clamp locations), however Verisurf cannot be 
set up to break up the data into groups representing each area between 
clamps.  The data points were taken in the proper order - it should be able 
to be copy/pasted into Art's analysis spreadsheet without too much hassle.

On this coil, Art has already determined that the PPPL and MTM measurements 
generally agree (pending some known bad points on the base that I 
remeasure).  My observation of the Leica data is that it also agrees with 
the existing data.
