• gets the pixel coordinates from PixCoords2x1, PixCoordsQuad, and PixCoordsCSPad classes,
• gets data from the event,
• produces the Image2D<double> or ndarray<double,2> or Image2D<double> object with CSPad image for each event,
• adds the image object in the event for processing in other modules.
  Time consumed to fill the CSPad image array (currently 1750x1750) is measured to be about 40 msec/event on psana0105.

...

• calibDir (default: "") – directory with calibration files, by default it is set to .../<experiment>/calib
• typeGroupName (default: "CsPad::CalibV1") – calibration type and group names,
• source (default: "CxiDs1.0:Cspad.0") – source of data,
• key (default: "") – key for data processing stage,
• imgkey (default: "Image2Dimage") – output key for image saved in event,
• events (default: 1<<31U) – number of events before stop a job,
• tiltIsApplied (default: true) – on/off for tilt angle of 2x1-sections and quads.
• print_bits (default: 0) – verbosity:
  • =0 - print nothing,
  • +1 - input pars,
  • +2 - calib pars,
  • +2 4 - consumed time per event,
  • +8 - information about image saved in event.

Remarks:

• By default the key corresponds to raw data.
• If the imgkey is defined as "Image2D", the image is saved in the event as a CSPadPixCoords::Image2D<double> object, otherwise (for other namesby default) as a ndarray<double,2> object.

...

• gets the pixel coordinates from PixCoords2x1, PixCoordsQuad, and PixCoordsCSPad classes,
• makes the arrays of neighbour addresses (quad, section, row, column) and weights as a function of the bin indexes (ix, iy) of the CSPad image,
• gets data from the event,
• produces the Image2D object with interpolated CSPad image for each event,
• adds the ndarray<double,2> or CSPadPixCoords::Image2D<double> or ndarray<double,2> object in the event for processing in other modules.
  In this module we use 4-node bi-linear interpolation algorithm.
  Time consumed to fill the CSPad image array (currently 1750x1750) is measured to be about 200 msec/event on psana0106. We consider options for acceleration using GPU or multi-core processing.

Module CSPadPixCoords::CSPadNDArrProducer

CSPadNDArrProducer is a module for psana framework. It uses specified source and inkey parameters,

• gets CSPAD configuration from the environment frame Psana::CsPad::ConfigV#,
• gets CSPAD data from the event frames Psana::CsPad::DataV#, Psana::CsPad::ElementV#,
• creates the image array as ndarray<T,3>, where T stands for {{outtype}, which may be double, float, int, or uint16_t,
• puts the image array in the event with outkey tag.

Module configuration parameters:

• source (default: ":Cspad.0") – source of data,
• inkey (default: "") – key for data processing stage,
• outkey (default: "cspad_ndarr") – output key for image saved in event,
• {{outtype} (default: "float") – type of output data,
• print_bits (default: 0) – verbosity:
  • =0 - print nothing,
  • +1 - input pars,
  • +4 - consumed time per event.
