2 years ago Unfortunately the Open Supernova Catalog has been down for some time and is no longer maintained. Mosfit can still be run on local data, so for now the solution is to find the object you need on the Github pages for the Open Catalogs.
E.g: https://github.com/astrocatalogs/sne-2010-2014/blob/master/SN2011ke.json
Download and run with
mostfit -e ./SN2011ke.json

2 years ago I see, thank you. I think it could be possible to rewire the code to download from Github. In any case, perhaps the docs at https://mosfit.readthedocs.io/en/latest/fitting.html#public-data could be updated to state that the instructions are outdated.
See #212.

2 years ago The problem isn’t so much the amount of work. Unfortunately since James left nobody is responsible for maintaining Astrocats, so I’m not sure who knows how to do it (not me!) or who would have any necessary permissions

Is it really too much work to renew the SSL certificate? That way the API with OACAPI https://github.com/astrocatalogs/OACAPI https://github.com/astrocatalogs/OACAPI would still work and restore all the other functionality. The website itself can remain broken.

2 years ago Hi all, apologies for this, my email reminder to renew the certs (as the renewal has to be done manually) got eaten by internet gremlins. I've renewed them now.
@JohannesBuchner there was a catastrophic database failure that killed the front end of the OSC/sister sites a few months back. This however did not kill the API, which is still active indefinitely. I have heard of two separate efforts to bring a replacement solution online but I do not know the timetables, until then my intention is to keep the API accessible.

Perhaps you have a cached name list on your computer and do not encounter the issue.

2 years ago Ah this is a different error, the JSON files are not being properly served. I'll take a look later today.

FYI kilonova.space registration lapsed and we no longer control that domain.

2 years ago It works now, thanks a lot!
The SSL certificate of https://sne.space/ expired last night (Wed, 07 Sep 2022 21:05:34 GMT)
This leads to mosfit examples failing with:
