[Issues] using external SourceLists

[Johannes Koppenhoefer]

Hello,

I tried to create a SourceList from an external LDAC/FITS catalog following the instructions in the manual on page 183 and using the AWBASE code.
It seems the method make_sourcelist_from_catalog() needs wcs information. Why is that, since the list already has ALPHA_SKY and DELTA_SKY?

Bye,
Johannes

awe> sl.catalog = 'variables.fits'
