Done for each batches above.
Pedestals
The pedestal calibration is performed for each block & run. When there is no response to LED lights, the block is marked as a potential bad block and is set arbitrarily to a pedestal value corresponding to the average pedestal value for the runs in which this block sees the LED lights.
Map of missing pedestals or blocks integrated over all runs
Change of the pedestal value from the nominal pedestal vs block number overall runs
Gain matching calibration plots
Checking the FCAL gains
Energy dependence correction monitoring plots
Bad block map
This map is done for each run number by combining the info collected by analyzing the LED and pi0 skims.
