ccdproc.combine input as numpy array

[ysBach]

ccdproc.combine currently accepts list or str, not numpy.ndarray.

I guess it is also quite common to have the filename as numpy.ndarray format, e.g., if I read a file named "file.list" using numpy.loadtxt.

So I want to ask whether there's any reason for accepting only list or str, not numpy.ndarray.

There are several unsupported formats: numpy.loadtext, hdf5, ...

combine is actually just a convenience function that supports FITS files and CCDData objects. It's likely noone had a use-case for numpy.loadtxt yet. If you don't need the chunked processing you can easily just pass in a list of CCDData:

filenames = [...]
ccds = [CCDData(np.loadtext(filename, ...)) for filename in filenames)
combine(ccds, ...)

@ysBach I have no objection to including it. I'd encourage you to contribute it, and if you need any help, just let us know.

Remilestoned, since we now have a PR to address this...thanks, @ysBach!
