# Simple basf2 steering file that creates mc file with PXDSimHits and
# EventMetaData needed for PXD gain calibration.
#
# Note that this script should only be used for runs in phase2 geometry
# with beams and magnetic field.
#
# Note that only SimHits from bg will be produced. A path to the mixer
# files for phase 2 must be specified. Only use for  runs with beam
# where most clusters are from bg.
#
# The command below will create reference mc file for gain calibration
# for run=3360 in exp=3 being part of the phase2 campaign.
#
# basf2 create_mcrun.py -- --tag='Calibration_Offline_Development'  --expNo=3 --runNo=3360 --setNo=0
