This module is supposed to run on dark cspad2x2 frame data. It calculates average and standard deviation values for each pixel and writes these values to output files in text format.

...

• source (default: "DetInfo(:Cspad)") – name of the data source; default value is adequate if there is only one CsPad device in setup, if there is more than one device then more specific value should be provided
• output (default: "cspad-pedestals.dat") – name of the output file for average values, if empty file will not be written
• noise (default: "cspad-noise.dat") – name of the output file for standard deviation values, if empty file will not be written

...

This should produce file pedestals.dat in the current directory. As the source address is more specific this configuration file can be used even if input data contain more than one CsPad device.

Module cspad_mod.CsPad2x2Pedestals

This module is supposed to run on cspad2x2 dark frame data. It calculates average and standard deviation values for each pixel and writes these values to output files in text format.

Module configuration parameters:

• source (default: "DetInfo(:Cspad2x2)") – name of the data source; default value is adequate if there is only one CsPad2x2 device in setup, if there is more than one device then more specific value should be provided
• output (default: "cspad2x2-pedestals.dat") – name of the output file for average values, if empty file will not be written
• noise (default: "cspad2x2-noise.dat") – name of the output file for standard deviation values, if empty file will not be written

To use this module with default parameters one could use this command:

psana -m cspad_mod.CsPad2x2Pedestals input-files.xtc

which will produce files cspad2x2-pedestals.dat and cspad2x2-noise.dat in the current directory (if input file contains CsPad2x2 data).

To change module parameters one could create file with name psana.cfg in the current directory with a contents like this:

[psana]
modules = cspad_mod.CsPad2x2Pedestals

[cspad_mod.CsPad2x2Pedestals]
source = DetInfo(CxiSc1.0:Cspad2x2.0)
output = pedestals.dat
noise =

and then run psana:

psana input-files.xtc

This should produce file pedestals.dat in the current directory. As the source address is more specific this configuration file can be used even if input data contain more than one CsPad2x2 device.
