Hi Rhys,
sorry that method isn't going to work for compressed images, just for
extensions with ordinary images. If you really don't want to use the HDU
browser to expand these for you, you'll need to do a little bit of
preprocessing. Either of:
% imcopy o20120527_00259.fits temp.fits
% gaia temp.fits'[4]'
% imcopy o20120527_00259.fits'[3]' temp.fits
% gaia temp.fits
should do it. Use the first version (which creates an MEF of uncompressed
images) if you are intending to inspect more than one image.
Cheers,
Peter.
