[QC on EPN]

rawDig_nClusters

To be checked:

  • The time stamp at the bottom should update every two 2 minutes during running.

  • When run is ongoing all Qualities in the list should be GOOD after 3 update cycles (6 minutes). In case of a BAD quality put log entry.

  • If in the quality trending, the quality is constantly BAD for multiple cycles (>10 minutes) call On-Call.

  • In case the Cluster task quality is BAD you can check if there are holes in the N cluster plots and inform OnCall.

  • If Only PID quality is BAD check if dEdx calculation is activated. If this is not the case the PID quality can be ignored. For the dEdx following parameter has to be in the EPN Extra ENV WORKFLOW_EXTRA_PROCESSING_STEPS=\"TPC_DEDX\" . This is typically diabled for PbPb running

  • For 1 MHz replay data the holes shown in the plot below are expected:

Known issues#

Occasionally, the 'Calib' QO may go red; this is an issue with the interplay of the validity of two objects. Please ignore if this behaviour is not persistent (work in progress).
