BCAL Calibration
From GlueXWiki
Steps in Calibration
- Remove 4ns ADC hardware offset (pass 1)
- Run reconstruction with BCAL_TDC_Timing plugin to produce the BCAL_TDC_Offsets/Deltat_raw/ histogram
- Run analysis script over output
- script for single run is /home/dalton/gluex/BCAL/monitoring/macros/extract_ADC_Dt_Zcorr.C
- /home/dalton/gluex/BCAL/monitoring/macros/monitor.py --adc4ns can be used to run over all runs
- Load constants to CCDB table /BCAL/ADC_timing_offsets using python macros/commit_CCDB.py -d output/ADCendDt/correction/ --adc
- Remove 32ns ADC hardware offset (pass 1)
- Set CCDB table /BCAL/TDC_offsets to 0
- Run reconstruction with BCAL_online plugin to produce the /bcal/bcal_Uhit_tdiff_raw_ave histogram (pass 1)
- Run analysis script over output
- script for single run is /home/dalton/gluex/BCAL/monitoring/macros/extract_Uhit_tdiff.C
- /home/dalton/gluex/BCAL/monitoring/macros/monitor.py can be used to run over all runs
- Load constants to CCDB table /BCAL/TDC_offsets using python macros/commit_CCDB.py -d output/tdiff/TDCcorrection/runs/ --tdc -v
- TDC timewalk correction (pass 2)
