A new Pull Request was created by @kskovpen (skkywriter) for CMSSW_7_1_X. It involves the following packages: SimMuon/MCTruth @cmsbuild, @civanch, @mdhildreth, @davidlange6 can you please review it and eventually sign? Thanks. cms-bot commands are listed here #13028 |

please test |
|
The tests are being triggered in jenkins. |

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_1_X IBs (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @smuzaffar |

@kskovpen , please, extend the PR description on top of this page specifically for 7_1_X (can be edited without a problem), also good to add a reference to a talk where usage of this is justified. |
|
@civanch Thanks. Done for both backport requests. |
|
@kskovpen David is asking to confirm where to filter (end of sim or start of digi). I suppose at the end of SIM as you probably don't want to write unuseful events out (I suppose the filter has quite low efficiency) and they would not be useful for other productions. Is this correct? Can you confirm? |
|
@perrozzi The expected filter efficiency is about 24%. Yes, probably, one should apply this filter at the end of SIM step to save some disk space. Yes, at the moment we would like to produce one dataset with this filter applied for preliminary tests within the BTV group to see if we can go for a massive production very soon. |

Backport of #16849 to 71X. It introduces a muon filter applied at G4 level to avoid the generator filter bias. Backport is needed to request the official dataset production.
