1. If the first and/or last event numbers are defined, then the filter will select events in this range only.
2. If the evtstring is defined, only listed events of event ranges will be selected. For example, the evtstring parameter can be defined as

   Code Block
   2,5,11-15,20-25,29,30

   that means the list of events:

   Code Block
   2 5 11 12 13 14 15 20 21 22 23 24 25 29 30

   In the evtstring parameter the comma "," and sign minus "-" as a dash are the only allowed separators. Blank spaces are also allowed. Other characters may abort the program. The evtstring mode has higher priority than the 1st mode.
   The filterIsOn allows easy turn on/off this filter in *.cfg file.

Module ImgAlgos::CSPadArrSaveInFile

This module saves the CSPad data array formatted as \[5920=4*8*185\]\[388\] in output file for each passes event.
Module configuration parameters:

• source (default: "DetInfo(:Cspad)") – input source of data
• key (default: "") – key for input data, for example, it might be "calibrated"
• outfile (default: "cspad-arr.dat") – out file with array of CSPad amplitudes
• print_bits (default: 0) – module verbosity:
  • =0 - print nothing,
  • +1 - input pars,
  • +2 - event ID.

Module ImgAlgos::CSPadArrAverage

This module averages the CSPad data array and saves two files for averaged and rms values in CSPad format \[5920=4*8*185\]\[388\]. In contrast to the [cspad_mod.CsPadPedestals|PCDS:Psana Module Catalog#Modulecspadmod.CsPadPedestals], the input data can be specified with a {{key}}, that allows to average CSPad array for already pre-processed data, for example {{"calibrated"}}. This feature can be used to evaluate the averaged signal or background event. Implemented algorithm of averaging allows to eliminate large statistical fluctuations in the pixel amplitude spectrum. In advanced case averaging may have up to three stages, depending on configuration parameters:
