# File:    detectorclocks_icarus_run5837pre09_22_03_01.fcl
# Purpose: DetectorClocks configuration appropriate to ICARUS minimum bias runs.
# Author:  Gianluca Petrillo (petrillo@slac.stanford.edu)
# Date:    May 17, 2021
# Version: 1.0
# 
# This DetectorClocksStandard configuration reflects the configuration of ICARUS
# minimum bias data runs like run 5837 decoded with `icaruscode` `v09_22_03`
# or earlier (not `v09_22_03_01` or later).
# 
# Until that version, PMT timestamps were set to 0.
# 
# In runs like 5837 there is a single PMT waveform per channel, acquired at beam
# gate opening time. TPC is acquired also based on beam gate (the trigger is
# common).
# The timestamp of PMT are not assigned and their value is stored as 0.
# This configuration aims to align those PMT waveforms with the TPC ones.
# 
# An important parameter is that the PMT waveform is set to 60% post-trigger
# (i.e. 10 out of 25 microseconds are collected before the beam gate opening).
# 
# This is an overriding configuration: include it after the main configuration;
# for example:
#     
#     #include "simulate_sliding_window_trigger_icarus.fcl"
#     #include "detectorclocks_icarus_run5252.fcl"
#     
#     # ... other overrides as needed
#     
# 
# Changes:
# 20210329 (petrillo@slac.stanford.edu) [v1.0]
#   original configuration
