BCAL Calibration

Steps in Calibration

1. Remove 4ns ADC hardware offset
   1. Set CCDB table /BCAL/TDC_offsets to 0
   2. Run reconstruction with BCAL_online plugin to produce the /bcal/bcal_Uhit_tdiff_raw_ave histogram
   3. Run analysis script over output
      1. script ifor single run is /home/dalton/gluex/BCAL/monitoring/macros/extract_Uhit_tdiff.C
      2. /home/dalton/gluex/BCAL/monitoring/macros/monitor.py can be used to run over all runs
   4. Load constants to CCDB table /BCAL/ADC_timing_offsets
2. Remove 32ns ADC hardware offset
   1. Set CCDB table /BCAL/TDC_offsets to 0
   2. Run reconstruction with BCAL_online plugin to produce the /bcal/bcal_Uhit_tdiff_raw_ave histogram
   3. Run analysis script over output
      1. script ifor single run is /home/dalton/gluex/BCAL/monitoring/macros/extract_Uhit_tdiff.C
      2. /home/dalton/gluex/BCAL/monitoring/macros/monitor.py can be used to run over all runs
   4. Load constants to CCDB table /BCAL/TDC_offsets
3. TDC timewalk correction
   1. Prerequisites:
      1. Remove 4ns ADC hardware offset
      2. Remove 32ns ADC hardware offset
   2. Run reconstruction with BCAL_TDC_Timing plugin
   3. Run analysis script over output
   4. Load constants to CCDB
4. Position from end time-difference
   1. Prerequisites:
      1. Remove 4ns ADC hardware offset
   2. Run reconstruction with BCAL_TDC_Timing plugin
   3. Run analysis script over output
   4. Load constants to CCDB
5. Calibrate the point time offset from tracking
6. Attenuation length and gain ratio
   1. Prerequisites:
      1. position calibration
