CalibFileFinder class finds the path to calibration file. Class constructor creates the object with elements of the path to the calibration file. When all input parameters are provided, the method findCalibFile(...) returns the path/name to the file with requested type of calibration parameters for indicated run number.

Class CSPadCalibPars

CSPadCalibPars class loads/holds/provides access to the CSPad geometry calibration parameters. Class constructor creates an object which loads and holds the calibration parameters of all CSPad geometry types. Access methods allows to extract parameters of all calibration types which are necessary for CSPad pixel coordinate geometryany of requested parameters.

Package CSPadPixCoords

Package CSPadPixCoords pre-calculates the 2x1 section, quad, and CSPad pixel coordinates and produces the image. CSPad image is also produced in combination of the pixel coordinates with event data.
For complete reference select Doxygen documentation.

...

Image2D class creates the object with a pointer to the 2D array containing image data and its sizes. It is assumed that the 2D array contains image data. Methods of this class provide access to the 2D array and its transformed versions after up-down, left-right flips, transpose, and rotations by n*90 degree.

Class QuadParameters

QuadParameters class holds object contains current parameters for of the CSPad quad. Object of this class is used to hold/pass current quad parameters.

Class PixCoords2x1

PixCoords2x1 class defines the 2x1 section pixel coordinates in its local frame.
Class constructor defines calculates the X, Y, and Z pixel coordinates for single 2x1 in its own (ONLINEmatrix style) frame: ; X coordinate is directed along ascending row index from 0 to 388 (from top to botton for 0 rotation angle). , Y coordinate is directed alond descending (ONLINE specific...) column index from 184 to 0 (from left to right for 0 rotation angle). The getPixCoorRot...(...) methods return these coordinates for rotated by N*90 degree 2x1 in um(micrometer) or pixels. Rows and columns are defined like described in ONLINE modules: /reg/g/psdm/sw/external/lusi-xtc/2.12.0a/x86_64-rhel5-gcc41-opt/pdsdata/cspad/ElementIterator.hh, Detector.hh
No parameters needed in constructor; everything is defined through the known 2x1 chip geometry.

...

PixCoordsQuad class defines the quad pixel coordinates in its local frame. Use the same frame like in The coordinate frame coinsides with that of optical measurement, but in "matrix style" geometry:

• X axis goes directed along rows ascending row index (from top to bottom)
• Y axis goes directed along columns ascending column index (from left to right)
  Pixel coordinates in quad are calculated using precise 2x1 section geometry from the class PixCoords2x1 and the calibration parameters extracted using by the PSCalib package.

Class PixCoordsCSPad

PixCoordsCSPad class fills defines and provides access to the CSPad pixel coordinates. Class constructor fills the arrays of the CSPad pixel coordinates , using the quad, section, row, and column indexesPixCoordsQuad class object and the calibration parameters extracted by the PSCalib package. Access methods return the CSPad pixel coordinate for indicated axis, quad, section, row, and column indexes. Pixel coordinates can be returned in um(micrometers), pix(pixels), or int(integer pixel index).

See description in Psana Module Catalog.

To execute this test module go to your release directory and run psana with appropriate configuration file:

cd <your-favorite-psana-release-directory>
psana -c CSPadPixCoords/data/psana_pixcoords_test.cfg

At the end of this test a few text files with images will be created:
test_2x1.txt, test_q0.txt, ..., test_q3.txt, and test_cspad.txt
To plot these image images you may use the python script, for example:

./CSPadPixCoords/data/PlotCameraImageFromFile.py test_q2.txt
...

Module CSPadImageProducer

...

To test this module go to your release directory and run psana with appropriate configuration file:

cd <your-favorite-psana-release-directory>
psana -c CSPadPixCoords/data/psana_cspad_image_producer.cfg

This procedure demonstrates that module is doing somthing, but does not produce show any useful results. The next module CSPadImageGetTest is intended to demonstrate results.
