[daip] Trouble loading X-ray FITS file

[Chun]

So I am trying to get a Chandra FITS file loaded into AIPS (FITLD), so I
can align
it with the radio images.

Here is the error:
URSA  > FITLD1: Task FITLD  (release of 31DEC03) begins
URSA  > FITLD1: FITS file of wrong type encountered, skipping
URSA  > FITLD1: CHNDAT:COULD NOT FIND FREQ AXIS
URSA  > FITLD1: FRQFID: ERROR   1 FROM CHNDAT OPCODE = READ
URSA  > FITLD1: ERROR      1 RETURNED FROM FRQFID
URSA  > FITLD1: Purports to die of UNNATURAL causes
URSA  > FITLD1: ursa         31DEC03 TST: Cpu=       0.0  Real=       0

Here are my inputs:

AIPS 1:                                    NCOUNT = 1)

Does AIPS even allow users to load it in?
