[AstroPy] specutils loading FITS file

[Nicholas Earl]

Hey James,

Specutils dev here. Specutils does not have a FITS loader for every data file (though we do have an extensive collection). I'd suggest following the documentation <https://specutils.readthedocs.io/en/latest/custom_loading.html#creating-a-custom-loader> on creating a custom data loader for your FITS file. Likewise, if you feel so inclined, you can submit a PR to the repository with the loader you create so that others trying to load similar data files won't have to create their own loaders.

If you're still unable to load the data file after having written your data loader (or need help writing the data loader), please open an issue on specutils github repo <https://github.com/astropy/specutils/issues>. We're eager to make specutils as usable as possible, so please let us know if you run into trouble.

Cheers,
Nick
