In details it correspond to BTauGenericMVAJetTagComputerRcd=MVAComputerContainer_75X_JetTags_v2_mc.\r\n\r\nThe effect is a slight improvement of the performance but, from the HLT point of view, there is a large increase of efficiency and trigger rate.\r\nIn the next DIGI-RECO campaign in 76X we want to simulate the trigger as close as possible to the real trigger used in data (in 74X). It means that we want to move back to the online b-taggin to the old training (while the offline b-tagging will continue to use the new training).\r\n\r\nThis PR adapts the HLT configuration in 76X to use the old b-tag training.\r\nThe code will work *only* on 75X_mcRun2_asymptotic_v9 and later (we need BTauGenericMVAJetTagComputerRcd=MVAComputerContainer_75X_JetTags_v3_mc).\r\n\r\nSo please approve the PR only when the the new GT will be available."},"comment":{"url":"https://api.github.com/repos/cms-sw/cmssw/issues/comments/150546633","html_url":"https://github.com/cms-sw/cmssw/pull/12062#issuecomment-150546633","issue_url":"https://api.github.com/repos/cms-sw/cmssw/issues/12062","id":150546633,"user":{"login":"fwyzard","id":4069793,"avatar_url":"https://avatars.githubusercontent.com/u/4069793?v=3","gravatar_id":"","url":"https://api.github.com/users/fwyzard","html_url":"https://github.com/fwyzard","followers_url":"https://api.github.com/users/fwyzard/followers","following_url":"https://api.github.com/users/fwyzard/following{/other_user}","gists_url":"https://api.github.com/users/fwyzard/gists{/gist_id}","starred_url":"https://api.github.com/users/fwyzard/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/fwyzard/subscriptions","organizations_url":"https://api.github.com/users/fwyzard/orgs","repos_url":"https://api.github.com/users/fwyzard/repos","events_url":"https://api.github.com/users/fwyzard/events{/privacy}","received_events_url":"https://api.github.com/users/fwyzard/received_events","type":"User","site_admin":false},"created_at":"2015-10-23T11:18:54Z","updated_at":"2015-10-23T11:18:54Z","body":"By the way, on second thought I would have preferred to use two different tags, rather than separate taggers within the same tag: it would be much easier to identify what is going to be used online or offline, and it would make it easier to update them independently."}}
