CPV KNOWN ISSUES

• In PEDESTAL runs QC plot "Pedestal sigma distribution M3 is bad". Acording to expert, noise conditions in CPV depend on general environment in ALICE, therefore, from time to time CPV pedestals can become wider which is reflected in QC-CPV calibration run plot with the message "Number of bad pedestal sigmas in module M3 (sometimes in M2) is larger than the upper limit". This is a known issue, can be ignored, but make a log entry when it happens. See: https://ali-bookkeeping.cern.ch/?page=log-detail&id=45015

• In PHYSICS runs Red messages on QC Plot "Digit Map in M4". Problem with high voltage is preventing this module from running normally. Experts are trying to recover. No need to report. Run quality must be setted to "good" if there are no problems with other modules. See: https://ali-bookkeeping.cern.ch/?page=log-detail&id=53523. Quality aggregator is also expected to show bad quality for Digit oocupancy check and CalibDigit amplitude check.
