Thank you, Nico.
However, I started now using pywcs, and I would probably stick to that
unless I cannot use the problem with it.
I am still quite confused why there are parallel packages doing mainly
the same thing: astLib and astrolib are quite for the same purpose, and
having both f.e. a wcslib wrapper. In my opinion, this parallel
development seems to me quite unnecessary and delays cooperation since
everyone historically uses his own preferred library. For different
programming languages, I could understand this, but I dont see a real
reason to have different pywcs modules.
Are there any attempts to unify the different approaches for
astro(python|lib)? What is the common opinion about the fragmentation
