Notes

Below are tables that can be updated with time-ordered publicly-released geometry files (most recent at top of table).

All geometry formats used by LCLS (cxidb, crystfel, cctbx, psana) can be placed here.  TJ TJ Lane has geometry-conversion scripts (currently psana/cheetah/crystfel, but cctbx will be added).  They can be obtained from github here:  https://github.com/LinacCoherentLightSource/psgeom

Below are tables that can be updated with time-ordered information (most recent at top of table):

• publicly-released geometry files
• comments for why new geometries might be needed (e.g. detector re-assembled, detector mis-cabled)

For use with all geometry formats used by LCLS (cxidb, crystfel, cctbx, psana).  This page would ideally include simple standalone scripts to convert between formats.

Optical measurements can be found HERE. Corrected optical metrology in text format can be found under the page CSPAD Alignment.Access to calibration files on disk /reg/g/psdm/detector/alignment/
