The [cleaning recommendation](https://twiki.cern.ch/twiki/bin/view/AtlasProtected/HowToCleanJets2016) is to reject events with any clean jets after your event selection.  Jet cleaning therefore needs to be the last event selection checked.  I.e. if the jet fails JVT, then cleaning should not be checked.  \r\n\r\nA new flag, m_cleanEvent, is introduced to remove events with one bad signal jet.  “m_cleanEvtLeadJets” (only removes event if first N jets are bad) is kept.\r\nThis also changes the order of the cutflow, but otherwise does not change the results for anyone who chooses not to use m_cleanEvent.\r\n\r\nThis update also removed the unprotected retrieve used in the METConstructor.\r\nIt also introduces an override of the AFII decision in ElectornCalibrator, in cases where the simulation metadata is not available in the derivation.\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/UCATLAS/xAODAnaHelpers/issues/comments/255220103","html_url":"https://github.com/UCATLAS/xAODAnaHelpers/pull/726#issuecomment-255220103","issue_url":"https://api.github.com/repos/UCATLAS/xAODAnaHelpers/issues/726","id":255220103,"user":{"login":"jdandoy","id":8410591,"avatar_url":"https://avatars.githubusercontent.com/u/8410591?v=3","gravatar_id":"","url":"https://api.github.com/users/jdandoy","html_url":"https://github.com/jdandoy","followers_url":"https://api.github.com/users/jdandoy/followers","following_url":"https://api.github.com/users/jdandoy/following{/other_user}","gists_url":"https://api.github.com/users/jdandoy/gists{/gist_id}","starred_url":"https://api.github.com/users/jdandoy/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jdandoy/subscriptions","organizations_url":"https://api.github.com/users/jdandoy/orgs","repos_url":"https://api.github.com/users/jdandoy/repos","events_url":"https://api.github.com/users/jdandoy/events{/privacy}","received_events_url":"https://api.github.com/users/jdandoy/received_events","type":"User","site_admin":false},"created_at":"2016-10-20T20:33:34Z","updated_at":"2016-10-20T20:33:34Z","body":"I've added the requested information.
