Following plot shows the evolution of eCAL CAL energy scale (average of 1536 crystals) over 4 years:
Next step is to arrange fully automatic generation of CAL calibrations every 6 Ms.
I use following procedure:
1) submit two batch jobs (asymmetry+pedestals and energy scale) for each group of 16 runs, producing MevperDAC histograms for each crystal and asymmetry histograms for each crystal segment (and pedestals for each channel).
- 120 jobs, ~few hours each
2) sum all generated histograms for each crystal or crystal segment
3) fit histograms and generate final calibration files.
For the moment I have several separate scripts, which I run manually one after another.
To make the procedure automatic, I just need to write master script which runs all steps sequentially and wait that all jobs from previous step are successfully finished before running next step.
