Verify if az_el_to_ra_dec is correct #86

Open github-actions[bot] opened 1 month ago

The results of this function in combination with the other coordinate system updates

for SGP4 give results similar to, but not identical to, the Skyfield results, so each

new conversion needs to be individually verified
