Bugs: wcs_update

Bugs

The wcsfile parameter doesn't accept the virtual file syntax (19 Aug 2011)

unix% pset wcs_update wcsfile="wcs.fits[bin sky=128]"

# wcs_update (CIAO): dsDMTABLEOPENERR -- ERROR: Failed to open a DM table in dataset ''. 
                         DM Error: '[dmi_block_parse_syntax]: null arguments'.
# wcs_update (CIAO): ERROR: Could not find WCS in wcsupdfile, and no separate wcsfile provided.

Workaround:

Copy the file before running wcs_update:

unix% dmcopy "wcs.fits[bin sky=128]" wcs.img
unix% pset wcs_update wcsfile=wcs.img
