Since the simulation time also goes down a lot beyond this value, I'm assuming there is some kind of cut-off? But I can't seem to find this in the code.\r\n\r\nThe simulation is set up to inject only photons at a certain redshift with a powerlaw spectrum. I'm using the EMCascade module to pass all photons to DINT immediately (I tried combined propagation, but altering the process method in a class inheriting from EMCascade doesn't seem to work). I did change the distance binning to have a maximum distance larger than the one I'm injecting the photons. Using the save method from EMCascade, I have verified that the histograms do contain photons before being passed to DINT.\r\n\r\nIs there anything I am missing?\r\n\r\nThanks!"},"comment":{"url":"https://api.github.com/repos/CRPropa/CRPropa3/issues/comments/381622629","html_url":"https://github.com/CRPropa/CRPropa3/issues/174#issuecomment-381622629","issue_url":"https://api.github.com/repos/CRPropa/CRPropa3/issues/174","id":381622629,"user":{"login":"TobiasWinchen","id":1299618,"avatar_url":"https://avatars0.githubusercontent.com/u/1299618?v=4","gravatar_id":"","url":"https://api.github.com/users/TobiasWinchen","html_url":"https://github.com/TobiasWinchen","followers_url":"https://api.github.com/users/TobiasWinchen/followers","following_url":"https://api.github.com/users/TobiasWinchen/following{/other_user}","gists_url":"https://api.github.com/users/TobiasWinchen/gists{/gist_id}","starred_url":"https://api.github.com/users/TobiasWinchen/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/TobiasWinchen/subscriptions","organizations_url":"https://api.github.com/users/TobiasWinchen/orgs","repos_url":"https://api.github.com/users/TobiasWinchen/repos","events_url":"https://api.github.com/users/TobiasWinchen/events{/privacy}","received_events_url":"https://api.github.com/users/TobiasWinchen/received_events","type":"User","site_admin":false},"created_at":"2018-04-16T14:40:15Z","updated_at":"2018-04-16T14:40:15Z","author_association":"OWNER","body":"The problem is in the  RedshiftBinsDown method of DINT using steps far from end.
