Steps in Calibration
- Remove 4ns ADC hardware offset
- Set CCDB table /BCAL/TDC_offsets to 0
- Run reconstruction with BCAL_online plugin to produce the /bcal/bcal_Uhit_tdiff_raw_ave histogram
- Run analysis script over output
- script ifor 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/ADC_timing_offsets
- Remove 32ns ADC hardware offset
- Set CCDB table /BCAL/TDC_offsets to 0
- Run reconstruction with BCAL_online plugin to produce the /bcal/bcal_Uhit_tdiff_raw_ave histogram
- Run analysis script over output
- script ifor 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
- TDC timewalk correction
