Alter to use fitsio instead of pyfits #1

Open simonrw opened 10 years ago

Pyfits is inefficient, whereas fitsio is a direct wrapper around cfitsio.

simonrw commented 10 years ago

I can convert most of the invokations of pyfits into fitsio, but when the 2mass cache is read fitsio cannot/won't decode one of the columns whereas pyfits will. For the time being as we're requiring astropy anyway this will have to remain an open issue.

With the latest version of fitsio this is possible, but I'm waiting until a release is made to pip so it can be tagged with a version number
