Currently, the Fits program's '--wcsdistortion' function can work on FITS HDUs that don't have any data. But this is only the case for SIP --> TPV conversion. The TPV --> SIP conversion needs an initial size for the dataset and will crash without it.

Great! Thanks Sachin, all the work was rebased into Commit 808c95dc56.
I also tested and it was reasonable: the reverse values weren't as accurate, but that is natural, its a fit after all ;-).
I am closing this task now.
