Hi Simon,

Thanks for your review and comments.

Yes it's a long journey to bring Julia's Astronomical projects to Guix.

Here is my plan:
https://git.sr.ht/~hellseher/ffab/tree/main/item/org/astronomy.org#L1202

cfitsio, wcs and erfa would be essential jll bindings for base Julia
packages.

I've got a question on how to group Julia packages related just to
Astronomy. gnu/packages/astronomy.scm contains python bindings to cfitsio,
wcs and erfa would I follow the same pass and add Julia packages next to
them?

Regards,
Oleg
