Optical measurement

Update

  • 2013-06-11 Modify script convertOpticalToStandard.py for indexing of rotated CSPAD
  • directly generated center_global/0-end.data constants
  • deployed to sxr65713
Note

Note from Chris:
The new metrology file is attached.  It has some unique characteristics.
1) all the positions are the same for 3 of the 4 quadrants
2) only the values for Quad 0 have changed.
3) this was done by aligning the entire detector to about 30 microRadians by hand.
4) This was checked by recording the positions of a few points on the other three quads
5) The slight rotation between last weeks and this weeks metrology can be taken out using these extra data points
