But something weird is definitely going on."},"comment":{"url":"https://api.github.com/repos/GalSim-developers/GalSim/issues/comments/208655003","html_url":"https://github.com/GalSim-developers/GalSim/issues/738#issuecomment-208655003","issue_url":"https://api.github.com/repos/GalSim-developers/GalSim/issues/738","id":208655003,"user":{"login":"rmjarvis","id":623887,"avatar_url":"https://avatars.githubusercontent.com/u/623887?v=3","gravatar_id":"","url":"https://api.github.com/users/rmjarvis","html_url":"https://github.com/rmjarvis","followers_url":"https://api.github.com/users/rmjarvis/followers","following_url":"https://api.github.com/users/rmjarvis/following{/other_user}","gists_url":"https://api.github.com/users/rmjarvis/gists{/gist_id}","starred_url":"https://api.github.com/users/rmjarvis/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/rmjarvis/subscriptions","organizations_url":"https://api.github.com/users/rmjarvis/orgs","repos_url":"https://api.github.com/users/rmjarvis/repos","events_url":"https://api.github.com/users/rmjarvis/events{/privacy}","received_events_url":"https://api.github.com/users/rmjarvis/received_events","type":"User","site_admin":false},"created_at":"2016-04-12T01:27:07Z","updated_at":"2016-04-12T01:27:07Z","body":"Oh, and currently, the cosmos_index value in the truth catalog will tell you which pairs go together.
