Dave,

Here is an improved version of the file I sent yesterday.
I have sorted out out a couple of minor bugs,
added some new columns of data, and tidied up the formatting. 
The file looks like this...

 SCc SCr CRc CRr CRx CRy     X        Y        Z        Pol      Azim
   1   3   1   1   1  11   15.916  321.770 3417.451    0.066    1.618
   1   3   1   2   1  12   15.916  352.215 3415.617    0.072    1.614
   1   3   1   3   1  13   15.916  382.663 3413.774    0.079    1.611
   1   3   1   4   1  14   15.916  413.113 3411.922    0.085    1.608
   1   3   1   5   1  15   15.916  443.567 3410.062    0.091    1.605
   1   3   2   1   2  11   45.035  321.775 3417.532    0.067    1.713
   1   3   2   2   2  12   45.036  352.220 3415.698    0.073    1.701
   1   3   2   3   2  13   45.036  382.668 3413.855    0.079    1.690
 etc

Where

SCc, SCr are the supercrystal column and row within the quadrant, 
CRc, CRr and the crystal column and row within the supercrystal,
CRx, CRy are the crystal X and Y coordinates within the quadrant,
(X,Y,Z) is the position of the centre of the rear face of the crystal, 
Pol,Azim are the polar and azimuthal angles of the crystal (and therefore VPT) axis.

If you need anything else added please let me know. 
Also, I can easily change the format of the file if required.

Bruce
