@slava77 , I can confirm that the default level is correct.
The DQM module is outdated, and will be updated after discussion with the global observable group.

• code changes affect only HI workflows;
• code review comments were addressed and no additional static analyzer issues are introduced
• jenkins tests passed OK; for comparisons with the baseline I'm relying on local tests (jenkins comparison jobs got stuck anyways)
• tested locally in CMSSW_7_5_0_pre4 /test area sign549/ also with 100 events in workflow 140.53 and 140.0
  • technical performance numbers were posted earlier in the thread
  • comparisons with baseline show differences only in the parts related to hiEvtPlane; DQM plots in Centrality/EventPlane are now picking up consistently "-10" default values for a default (unfilled) level index.
• DQM code still needs updates
