It allows to reconstruct image using generic Detector Geometry technique with geometry file. Current version of pnCCD has a solid structure without moving parts, so hence the main part of the geometry file is unchanged. Example of the geometry file for pnCCD can be found under in /reg/g/psdm/detector/alignment/pnccd/amo-pnccd.1-2015-01-23/calib. The last commented line in this file can be uncommented in order to rotate and translate detector relative to IP.-2015-01-23/calib/PNCCD::CalibV1/Camp.0:pnCCD.1/geometry/0-end.data, which essential part is

The last commented line in this file can be un-commented in order to rotate and translate detector relative to IP.

Note

  • The name of the segment PNCCD:V1 should be unchanged. Other names DETPNCCD:V1 and IP:V1 are optional.
  • Four segment coordinates are given in µm and it is assumed that each segment has 512x512 pixels of size 75x75µm².
  • All coordinates are given in matrix-like frame, where X axis goes from top to bottom, Y - from left to right.
  • Gap is set to 16 pixels and may be a subject of calibration.

...

  • ImgAlgos.PnccdNDArrProducer  - det gets pnCCD data and put it as ndarray in the event store
  • ImgAlgos.NDArrCalib - apply applys calibrations to ndarray
  • ImgAlgos.NDArrImageProducer - produces calibrated image
  • ImgAlgos.NDArrAverage:nda - averages calibrated ndarray
  • ImgAlgos.NDArrAverage:img-geo - averages calibratedimage
