So, if people don't want to go through the direction dependent process it would be good to give the option of primary beam corrected images.\r\n\r\nI guess there are two ways of doing this, the first being to change the bbs calibration to not remove the beam and then allowing the user to image the data themselves. Alternatively, perhaps the option that would result in accidental operations errors would be to have a switch in the parset to enable primary beam correction the high2 images made during the source subtraction (wsclean has the beam now? or could just do similar to factor and use awimager pbimages to correct the images)."},"comment":{"url":"https://api.github.com/repos/lofar-astron/prefactor/issues/comments/247609530","html_url":"https://github.com/lofar-astron/prefactor/issues/38#issuecomment-247609530","issue_url":"https://api.github.com/repos/lofar-astron/prefactor/issues/38","id":247609530,"user":{"login":"twshimwell","id":12065270,"avatar_url":"https://avatars.githubusercontent.com/u/12065270?v=3","gravatar_id":"","url":"https://api.github.com/users/twshimwell","html_url":"https://github.com/twshimwell","followers_url":"https://api.github.com/users/twshimwell/followers","following_url":"https://api.github.com/users/twshimwell/following{/other_user}","gists_url":"https://api.github.com/users/twshimwell/gists{/gist_id}","starred_url":"https://api.github.com/users/twshimwell/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/twshimwell/subscriptions","organizations_url":"https://api.github.com/users/twshimwell/orgs","repos_url":"https://api.github.com/users/twshimwell/repos","events_url":"https://api.github.com/users/twshimwell/events{/privacy}","received_events_url":"https://api.github.com/users/twshimwell/received_events","type":"User","site_admin":false},"created_at":"2016-09-16T14:07:18Z","updated_at":"2016-09-16T14:07:18Z","body":"In v2.0 André has kindly implemented this feature --  https://sourceforge.net/p/wsclean/tickets/82/ so it could go into initsubtract now"}}
