BUG:	A segmentation error can occur when using a WIYN/HYDRA image for the
	aperture identification information.  The workaround is to use a text
	aperture identification file rather than the image.  One can use
	the supplied '.iraf' file or create a file from the header.  The
	following command can easily generate an aperture identification
	file from the contents of the image header.

	    cl> hselect  SLFIB* yes | translit STDIN ''' '
' > apid

	This will have blank lines between the entries but they are ignored
	by DOHYDRA.

STATUS:	Fixed for the next release.
