How good was the agreement?  Did you check the catalog magnitudes, colors or both?\r\n\r\nThe galaxy input catalog schema is documented [here](https://confluence.lsstcorp.org/display/SIM/Database+Schema) (@danielsf is this still current?)"},"comment":{"url":"https://api.github.com/repos/DarkEnergyScienceCollaboration/WeakLensingDeblending/issues/comments/238727090","html_url":"https://github.com/DarkEnergyScienceCollaboration/WeakLensingDeblending/issues/17#issuecomment-238727090","issue_url":"https://api.github.com/repos/DarkEnergyScienceCollaboration/WeakLensingDeblending/issues/17","id":238727090,"user":{"login":"dkirkby","id":185007,"avatar_url":"https://avatars.githubusercontent.com/u/185007?v=3","gravatar_id":"","url":"https://api.github.com/users/dkirkby","html_url":"https://github.com/dkirkby","followers_url":"https://api.github.com/users/dkirkby/followers","following_url":"https://api.github.com/users/dkirkby/following{/other_user}","gists_url":"https://api.github.com/users/dkirkby/gists{/gist_id}","starred_url":"https://api.github.com/users/dkirkby/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/dkirkby/subscriptions","organizations_url":"https://api.github.com/users/dkirkby/orgs","repos_url":"https://api.github.com/users/dkirkby/repos","events_url":"https://api.github.com/users/dkirkby/events{/privacy}","received_events_url":"https://api.github.com/users/dkirkby/received_events","type":"User","site_admin":false},"created_at":"2016-08-09T23:48:54Z","updated_at":"2016-08-09T23:48:54Z","body":"On the topic of extinction, the schema says for, e.g. `ext_model_b`:\r\n```\r\nExtinction model identifier ('ccm')\r\n```\r\nI guess `ccm` refers to [Cardelli, Clayton & Mathis (ApJ, 345, 245, 1989)](http://adsabs.harvard.edu/abs/1989ApJ...345..245C), but this appears to be Milky Way (not host galaxy) extinction, so shouldn't it depend on the (ra,dec) of an observation, which isn't fixed for a catalog object because of the tiling?"}}
