NDF2FITS has a new literal parameter called AXISORDER to specify the order of WCS axes in the output FITS header. This is introduced so that the generated FITS file may be interpeted correctly by those FITS readers that assume certain axis orders. For example some expect equatorial co-ordinates to be ordered right ascension then declination, whereas the FITS standard lets you permute WCS axes in any order.
IRAF release V2.11.3 libraries are used in this release for building NDF2IRAF and IRAF2NDF.
