Is it possible to add the WCS rotation information to the fits header? I’m using software that uses the WCS information and am finding the CROTA2 information missing in the header. Specifically, it would be nice to see:
- CDELT1 = -0.000666667 / Degrees/pixel
- CDELT2 = 0.000666667 / Degrees/pixel
- CROTA2 = 0.00000 / Rotation in degrees.
Here’s a link to the description:

Thanks!
