Data for alignment: exp=cxi86715:run=112

  EventKey(type=Psana::CsPad2x2::ElementV1, src=DetInfo(CxiDg2.0:Cspad2x2.0), alias="Dg2CsPad2x2")
  EventKey(type=Psana::CsPad::DataV2, src=DetInfo(CxiDs2.0:Cspad.0), alias="DsaCsPad")

  • It looks like CSPAD geometry has an offset relative to the beam center
  • If chosen orientation is correct, based on vertical pattern seen on CSPAD2x2 the distance between strike and barely visible 2x1 boarder is 146pix in CSPAD2x2 and 41 in CSPAD, that gives scale factor 3.56.
  • then CSPAD2x2 (x,y)  position can be adjusted relative to CSPAD.
  • CSPAD2x2 geometry file
  • we think the relative orientation of cspad2x2 and big cspad is correct because of the "bulb" on the right side of both the above images, but this is not 100% robust.
