In most use cases, `mu1` is actually used to represent `zmu1`. It might be worthwhile to phase out mu1 in favor for `zmu1` and complete the `zmuX` quantities.\r\n\r\nIn case of `muplus`/`muminus`, this seems to be not an issue, as they are by design meant to be `zmuplus`/`zmuminus`. Any differences are an error in `muplus`/`muminus`. For `mu1`, there is technically a valid difference, however.\r\n\r\nMy questions: should `mu1` be phased out in favor of `zmu1`? Should the names also be changed from `zmu1` to just `mu1`?"},"comment":{"url":"https://api.github.com/repos/artus-analysis/Excalibur/issues/comments/149440088","html_url":"https://github.com/artus-analysis/Excalibur/issues/37#issuecomment-149440088","issue_url":"https://api.github.com/repos/artus-analysis/Excalibur/issues/37","id":149440088,"user":{"login":"dhaitz","id":5802753,"avatar_url":"https://avatars.githubusercontent.com/u/5802753?v=3","gravatar_id":"","url":"https://api.github.com/users/dhaitz","html_url":"https://github.com/dhaitz","followers_url":"https://api.github.com/users/dhaitz/followers","following_url":"https://api.github.com/users/dhaitz/following{/other_user}","gists_url":"https://api.github.com/users/dhaitz/gists{/gist_id}","starred_url":"https://api.github.com/users/dhaitz/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/dhaitz/subscriptions","organizations_url":"https://api.github.com/users/dhaitz/orgs","repos_url":"https://api.github.com/users/dhaitz/repos","events_url":"https://api.github.com/users/dhaitz/events{/privacy}","received_events_url":"https://api.github.com/users/dhaitz/received_events","type":"User","site_admin":false},"created_at":"2015-10-20T05:45:51Z","updated_at":"2015-10-20T05:45:51Z","body":"I think for mu1/2/plus/minus one always wants the muons from Z decay, so yes (to both questions)"}}
