Chandra FITS images compatibility with IRAF

Hi,

I'm trying to read an ACIS FITS image with IRAF. For example, I'm just
trying to display it onto Saoimage:

cl>display acis.fits
ERROR: FXF: must specify which FITS extension (acis.fits)

Does anyone know what this error message means?

The image displays on ds9 fine but won't display onto Saoimage.

Thanks,

Teddy
