All geometry formats used by LCLS (crystfel-hdf5, crystfel-cxidb, cctbx, psana) can be placed here.  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.

Information about methods to convert geometry files between different formats can be found here.

Optical measurements can be found HERE. Corrected optical metrology in text format can be found under the page CSPAD Alignment.

...

Note the DS1 and DS2 chambers can move to different locations. Also, Camera1 and Camera2 can move between DS1 and DS2 chambers. Sample chambers, SC1-SC3 are fixed.

Camera2_V16_20160205

Geometry file optimized using lysozyme.

The xxx in cxi02416_xxx.geom represents the camera length.

The detector was translated in x & y w.r.t powder ring and detector_shift script was used to correct for offset.

	Based on dubrovin's psana geometry, tweaked x,y,z detector position with psocake to optimize indexing results. Prediction refine / geoptimization was NOT performed.
