Test of the NDArrCalib module for pnCCD.

 

Module ImgAlgos::PixCoordsProducer

Functionality

For data source  in each run loads/updates calibration geometry file from the calibration DB, evaluates pixel coordinate arrays using class PSCalib::GeometryAccess and saves them as ndarray<const float,1> in the event store for keywords x-pix-coords, y-pix-coords, and z-pix-coords.

The main idea of this module is that calibration geometry file will be found and loaded (if available) automatically.

verbosity:

  • =0 - print nothing
  • +1 - input pars
  • +2 - calibration file path
  • +4 - list of geometry objects
  • +8 - list of geometry objects with children
  • +16- comments from calibration file
  • +32 - pixel coordinates

Current version of this module works with CSPAD and CSPAD2x2. It can be extended for other detectors, whenever necessary.

Module ImgAlgos::ImgAverage

This module averages over events the per-pixel data of the image array (ndarray<const double,2>) and saves files for averaged, rms values, and, if requested, the hot pixel mask. Input data can be specified by the source and key parameters. Averaging may have up to three stages, depending on configuration parameters:
