This PR includes configurable modifications to the EMTF track-building sequence which reduce the rate without efficiency loss, especially in high-pileup conditions.  Configurable track-building parameters as follows:\r\n* Window of BX included in same track adjustable (1 - 3 BX)\r\n* Reduced theta window between LCTs in Zone 0 (high eta)\r\n* Fix to theta ambiguity when two LCTs are in the same chamber\r\n* Removal of two-station tracks with LCTs in different BX\r\n* Improved track mode <---> uGMT quality mapping\r\n\r\nBest regards,\r\nAndrew"},"comment":{"url":"https://api.github.com/repos/cms-sw/cmssw/issues/comments/385920022","html_url":"https://github.com/cms-sw/cmssw/pull/23109#issuecomment-385920022","issue_url":"https://api.github.com/repos/cms-sw/cmssw/issues/23109","id":385920022,"user":{"login":"cmsbuild","id":4170616,"avatar_url":"https://avatars1.githubusercontent.com/u/4170616?v=4","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":"2018-05-02T09:33:37Z","updated_at":"2018-05-02T09:33:37Z","author_association":"CONTRIBUTOR","body":"+code-checks\n\nLogs: https://cmssdt.cern.ch/SDT/code-checks/cms-sw-PR-23109/4527"}}
