bklm-pocketdaq.py

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
 
 
 
# Purpose:
#   Analyze PocketDAQ data created by the test stand at Indiana University
#   and write a PDF file of the resulting histograms/scatterplots.
#
# Prerequisites (on kekcc):
#   Before running this script, type
#     source /cvmfs/belle.cern.ch/tools/b2setup release-02-01-00 <or higher release>
#   and translate the test-stand raw data file to a ROOT file using Richard Peschke's app
#
# Usage:
#   basf2 bklm-pocketdaq.py -- -i infilename -e # -r # -n # -f #
#   You need the '--' before these options to tell basf2 that these are options to this script.
#   Required argument:
#      -i infilename  to specify the full pathname of the input ROOT file
#   Optional arguments:
#      -e #   to specify the experiment number, e.g., -e 1 (no default)
#      -r #   to specify the run number, e.g., -r 0109 (no default)
#      -n #   to specify the number of events in the run to be processed (no default -> all events)
#      -f #   to filter only the even-numbered events (-f 0) or the odd-numbered events (-f 1) (no default -> all events)
#
# Input:
#   ROOT file written by Richard Peschke's translator app whose input was a test-stand raw data file. For example,
#   /home/belle2/dbiswas/Documents/PocketDAQ/klm_offline_entpacker/build/klm_unpacker/brandon_data/dblpls_30k_fine_20190109.root
#
# Output:
#   ROOT histogram file named bklmHists-e#r#.root, using the experiment number and run number
#   PDF file named bklmPlots-e#r#.pdf, using the experiment number and run number
#
