[daip] FITLD trouble with HST image.

I have a processed HST image that I once loaded into AIPS, I think (I have
AIPS images derived from it), but that will not load now. The messages
after the temporary file is created are:
FITLD1: IMPARS: BAD NUMBER ON EQUINOX
FITLD1: TABHDR: NUMBER OUT OF RANGE ON CRVAL1
FITLD1: ERROR 1 RETURNED FROM IMGTAP
Looking at the FITS header with less, CRVAL1 looks reasonable (68.29....)
which is what it should be.
I don't see an Equinox specification until fairly far down the header
(under EXPOSURE INFORMATION), but it is there.
The image is rotated -65.3... degrees from the normal celestial coordinates.
Instead of CDELT values, this image has CD1_1 (-5.28E-6), CD1_2 (-1.14E-5),
CD2_1 (-1.14E-5), and CD2_2 (5.278E-6) (I did not give the numbers to their
full precision). Note that CD1_1 is not quite equal to -CD2_2 and CD1_2
is not quite CD2_1.
If you need more, I can provide the image.
Cheers,
Craig
