Dear Astropy,
In the project I'm working on (SVOM), I have to resolve image astrometry
with parameters given as IRAF at ccmap input files (*.db).
I've pasted a sample below.
As I'm not an IRAF user and my application is Python based, I would like
to know whether someone in the community would have some experience with
handling such coordinate transformations with AstroPy or some associate
package.
Regards
LM
