Attached, the latest metrology file for the XPP CSPAD Camera 3. It should be applied to all experiments taken after August 19, 2016. Experiments before that date should use the previous metrology file (2013-10-09). Quad 3 has been repaired; quads 0, 1, and 2 should match the previous metrology file. As always, please use Mikhail’s metrology file. The raw file provided here is known to contain occasional inaccuracies.

Check alignment
Data and calibrations for test
It was reported by instrument scientist that new geometry does not work.
Silke pointed good example to check: xppo5616 run 716
Calibration files in
/reg/d/psdm/xpp/xppo5616/calib/CsPad::CalibV1/XppGon.0:Cspad.0/geometry/
- file 0-end.data
- file 1-end.data is the same as 0-end.data in archive
- file 2-end.data is from Chapmen's group on # AUTHOR yefanov # DATE_TIME 11-9-2016 18:07:31.205787
Images for metrology and Chapmen's group geometry:
- Numeration of quads is the same...
- optical metro geometry shows significant offsets between quads
- chapman's geometry fixs offset problem
So, what is wrong with metrology?
Apparently numeration of quads in metrology measurement and in camera connection to controller are mismatched by -1 (90 degree contra clock-wise direction on image).
Fixed geometry from optical metrology is in
/reg/g/psdm/detector/alignment/cspad/calib-xpp-2016-08-22-camera3/
Silke checks if it works...
