[[Originally submitted by Alex in bug-gnuastro, see there for the data]]

I am trying to transform the coordinate system of a WCS from B1950 to J2000 using Gnuastro 0.19, wcslib 7.12. The original fits file is attached. When I run the following command:


astfits -h1 NGC6946_scaled.fits --wcscoordsys=eq-j2000


The new fits file (NGC6946_scaled-eq-j2000.fits, also attached) contains the same header, without any changes. ec-j2000 works, so I guess that the installation is ok, but that is not the system I need. I am doing something wrong?
