Detailed Description

Module to synchronize parallel measurements with the old and new DAQ.

Author:

Laura Kogler

Usage: First run MTimeSort and save output to a file to obtain a sorted list of times from the old DAQ. Then run this module on the new DAQ data with the old DAQ sorted list as the input parameter "ComparisonFile". The output of the module is a time offset between the "NsTime" of the input file and the "NsTime" of the comparison file.

• Config example:

      module SynchronizeMeasurements
      verbosity = info
      enable = true
      ComparisonFile = sorted.txt
      OutputFile = results.txt
      Window = 500.0
      Range = 10.0
      endmod
      

• Parameters
  • ComparisonFile [string = NODEFAULT]: File containing a sorted list of times in milliseconds "TimeMs" and the unix start time of the run "RunStartTime"
  • Window [double = 500.]: Time window around points to use (in ms)
  • Range [double = 10.0]: Range of offsets to scan in seconds (0 +/- this number)
  • OutputFile [string = synch.txt]: Filename for output. If it is a root file it saves a TGraph of results; ascii file will save QVectors.

• Reads:
  • QRawData
  • QASCII

• Writes
  • QASCII/external root file
