This means we have a significant (up to 30 clock ticks) amount of walk for low energy gammas.\r\n\r\nTime shifts in general could effect the event construction, the events that pass the \"coincidence\" window, and the addback algorithms. As long as we keep such a large time window for event construction, the effect of a walk correction there would be minimal. It's fairly easy to execute the correction before judging \"coincident\" events in MakeMatrices. The problem we're encountering right now is how to incorporate this into the creation of the addback hits.\r\n\r\nIs there existing infrastructure that we could take advantage of to implement a walk correction? If there is no existing infrastructure, are there pre-existing ideas/plans for implementing this? I imagine this might be related to implementations of the CFD sub-timestamp correction, but I haven't located where that occurs in the code."},"comment":{"url":"https://api.github.com/repos/pcbend/GRSISort/issues/comments/89025155","html_url":"https://github.com/pcbend/GRSISort/issues/252#issuecomment-89025155","issue_url":"https://api.github.com/repos/pcbend/GRSISort/issues/252","id":89025155,"user":{"login":"r3dunlop","id":5428160,"avatar_url":"https://avatars.githubusercontent.com/u/5428160?v=3","gravatar_id":"","url":"https://api.github.com/users/r3dunlop","html_url":"https://github.com/r3dunlop","followers_url":"https://api.github.com/users/r3dunlop/followers","following_url":"https://api.github.com/users/r3dunlop/following{/other_user}","gists_url":"https://api.github.com/users/r3dunlop/gists{/gist_id}","starred_url":"https://api.github.com/users/r3dunlop/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/r3dunlop/subscriptions","organizations_url":"https://api.github.com/users/r3dunlop/orgs","repos_url":"https://api.github.com/users/r3dunlop/repos","events_url":"https://api.github.com/users/r3dunlop/events{/privacy}","received_events_url":"https://api.github.com/users/r3dunlop/received_events","type":"User","site_admin":false},"created_at":"2015-04-02T19:54:35Z","updated_at":"2015-04-02T19:54:35Z","body":"So as it stands, we have to go through and type a WALK in for every channel in the cal file?\r\nFor reference here is my fit:\r\n![screenshot 2015-04-02 15 45 10](https://cloud.githubusercontent.com/assets/5428160/6972265/875a0752-d950-11e4-9335-9be7e4906414.png)\r\n![screenshot 2015-04-02 15 48 14](https://cloud.githubusercontent.com/assets/5428160/6972267/88937a2c-d950-11e4-8213-7502d08e1aa1.png)\r\n"}}
