When an image passes through the starting point of RA, the output is not reasonable:


$ wget http://archive.cefca.es/catalogues/vo/siap/jplus-dr2/get_fits?id=71811 -Ojplus-dr2-71811.fits.fz

$ astfits jplus-dr2-71811.fits.fz --skycoverage
Input file: jplus-dr2-71811.fits.fz (hdu: 1)

Sky coverage by center and (full) width:
  Center: 0.7156         3.2553
  Width:  359.2663831    1.465812035

Sky coverage by range along dimensions:
  RA       0.7156         359.9819831
  DEC      2.52212733     3.987939365


As seen above, the width is ~359 degrees and the RA goes from 0.7 to 359! We should be able to account for such situations.
