Validation code for BTagging at HLT

[silviodonato]

Re-ope of PR #5387

It is a validation code for the b-tagging at HLT.
It was presented in the DQM meeting : https://indico.cern.ch/event/294162/

News:

• implemented comments by @deguio
• integration of the validation in the central validation sequence (added in hltValidation of HLTriggerOffline/Common)
• tested with "python whiteRabbit.py" Align documentation to migrated repository. #3 and Test feature #4 , with small changes:
  • I'm using TTbar, instead of SingleMu, in order to have few jets, needed for b-tagging.
  • I'm also using the HLT:FULL menu, as it always run b-tagging (if you think the code has to use HLT:GRun, I can change quickly the code).
• Although I propose to add the code in the central validation sequence, I'd like to maintain the code used for a private b-tag validation (config.ini, test.py, .....)

@silviodonato - seems this is crashing a number of IB tests - could you fix asap

Eg:
https://cmssdt.cern.ch/SDT/cgi-bin/buildlogs/slc6_amd64_gcc481/CMSSW_7_3_X_2014-11-08-0200/pyRelValMatrixLogs/run/1312.0_ZpMM_13+ZpMM_13INPUT+DIGIUP15+RECOUP15+HARVESTUP15/step3_ZpMM_13+ZpMM_13INPUT+DIGIUP15+RECOUP15+HARVESTUP15.log

Reverting this so that the IBs will be more successful. Please resubmit when fixed.

Hi,
I've corrected the code: https://github.com/silviodonato/cmssw/tree/btag-hlt

In very few events it happened that HLT_PFMET170_NoiseCleaned_v1 pass, but no b-tag variables were reconstructed (although HLT_PFMET120_NoiseCleaned_BTagCSV07_v1 use lower threshold).
This because HLT_PFMET120_NoiseCleaned_BTagCSV07 use also a cut on "hltMETCleanUsingJetID80".

Now, I select only events that pass HLT_PFMET120_NoiseCleaned_BTagCSV07, so we have BTag variables for sure.

Do I need to ask a new PR?

Thanks,
Silvio.
