Follow-up Comment #2:

Thanks again for this great description and wonderful suggestion. The issue
has been fixed and pushed
<http://git.savannah.gnu.org/cgit/gnuastro.git/commit/?id=932100> to the main
repository.

The fact that the `CDELTi's were 1 was always bothering me, I just didn't have
the motivation to fix it. Thanks a lot for the very clear and motivating
description of this bug and also bug #50072 ;-). It would be great if WCSLIB
could implement the Singular Value Decomposition also when reading from
`CDi_j' inputs instead of simply setting all the `CDELTi' to 1. 

You can try out any change that is pushed to the main repo. I have the
described in bug #50072 (with links to the book). If you can't do
bootstrapping immediately, just let me know and I will send you the tarball
for Gnuastro version 0.2.57-9321 privately.
