There is also a h5parm with all the solutions\r\n\r\nWhy dont we change this by adding a step at the end that simply takes CORRECTED_DATA (using msout.storage.manager=dysco) from each 10sb block and putting this into a new file. These new files would then be the final products and would be much smaller than the existing products.\r\n\r\nI know this is incompatible with FACTOR at present. But, in the short term, one could easily make it compatible again by artificially redoing the GSM cal to create a new CORRECTED_DATA column if you wanted to do so.\r\n"},"comment":{"url":"https://api.github.com/repos/lofar-astron/prefactor/issues/comments/424272240","html_url":"https://github.com/lofar-astron/prefactor/issues/184#issuecomment-424272240","issue_url":"https://api.github.com/repos/lofar-astron/prefactor/issues/184","id":424272240,"node_id":"MDEyOklzc3VlQ29tbWVudDQyNDI3MjI0MA==","user":{"login":"darafferty","id":5547918,"node_id":"MDQ6VXNlcjU1NDc5MTg=","avatar_url":"https://avatars3.githubusercontent.com/u/5547918?v=4","gravatar_id":"","url":"https://api.github.com/users/darafferty","html_url":"https://github.com/darafferty","followers_url":"https://api.github.com/users/darafferty/followers","following_url":"https://api.github.com/users/darafferty/following{/other_user}","gists_url":"https://api.github.com/users/darafferty/gists{/gist_id}","starred_url":"https://api.github.com/users/darafferty/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/darafferty/subscriptions","organizations_url":"https://api.github.com/users/darafferty/orgs","repos_url":"https://api.github.com/users/darafferty/repos","events_url":"https://api.github.com/users/darafferty/events{/privacy}","received_events_url":"https://api.github.com/users/darafferty/received_events","type":"User","site_admin":false},"created_at":"2018-09-25T09:31:52Z","updated_at":"2018-09-25T09:31:52Z","author_association":"CONTRIBUTOR","body":"Yes, but Factor expects the SUBTRACTED_DATA_ALL column to be uncorrected (e.g., it corrupts the models with the dir-indep soutions before adding/subtracting them). I guess we could change Factor instead, but aren't there are some advantages to using the uncorrected data in selfcal (e.g., fewer free parameters)?"}}
