[AstroPy] IRAF tasks to Astropy

[Sofia Lianou]

Of the three tasks mentioned below, the mkpattern and ccsetwcs can be dealt within astropy alone. The wregister is not clear how to deal with only using astropy or scipy, unless thinking of doing this from scratch. Thus, I am interested in alternatives to wregister within python (but not pyraf), with the following use:wregister input.fits reference.fits output.fits fluxconserve=yes


Thanks,
Sophia
