We added a protection in the combination code to only use the Ep combination MVA at high energies when the track pT error is smaller than 10 times the track pT. It is a pretty safe cut that removes these badly measured tracks from the determination of the electron energy.\r\n\r\nReference: https://hypernews.cern.ch/HyperNews/CMS/get/physTools/3446/1/1/1/1.html"},"comment":{"url":"https://api.github.com/repos/cms-sw/cmssw/issues/comments/184751006","html_url":"https://github.com/cms-sw/cmssw/pull/13301#issuecomment-184751006","issue_url":"https://api.github.com/repos/cms-sw/cmssw/issues/13301","id":184751006,"user":{"login":"cmsbuild","id":4170616,"avatar_url":"https://avatars.githubusercontent.com/u/4170616?v=3","gravatar_id":"","url":"https://api.github.com/users/cmsbuild","html_url":"https://github.com/cmsbuild","followers_url":"https://api.github.com/users/cmsbuild/followers","following_url":"https://api.github.com/users/cmsbuild/following{/other_user}","gists_url":"https://api.github.com/users/cmsbuild/gists{/gist_id}","starred_url":"https://api.github.com/users/cmsbuild/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/cmsbuild/subscriptions","organizations_url":"https://api.github.com/users/cmsbuild/orgs","repos_url":"https://api.github.com/users/cmsbuild/repos","events_url":"https://api.github.com/users/cmsbuild/events{/privacy}","received_events_url":"https://api.github.com/users/cmsbuild/received_events","type":"User","site_admin":false},"created_at":"2016-02-16T16:17:02Z","updated_at":"2016-02-16T16:17:02Z","body":"+1\nTested at: 09ad603d8a89007ae9608b4f4bf843edc1aa0d0e\nhttps://cmssdt.cern.ch/SDT/jenkins-artifacts/pull-request-integration/PR-13301/11250/summary.html"}}
