Psana with this script runs over 1000 events and produces file files

  • acq-amo01509-r0125-config.txt -- with Acqiris configuration parameters
  • acq-amo01509-r0125-ave-wfs.txt with averaged array of waveforms:

This scriptworks script works with psana as follows:

  • for the 1st 1000 events averages waveforms below thresholds and saves results in the file acq-bline-amo01509-r0125-ave-wfs.txt;
  • for the next 1000 events subtracts baseline level and averages waveforms above thresholds and saves results in the file acq-signal-amo01509-r0125-ave-wfs.txt.
