Details:
Currently there is no easy way in the Fits program
<http://www.gnu.org/software/gnuastro/manual/html_node/Fits.html> to
identically copy multiple keywords from one FITS file/HDU into another
file/HDU.
There was a simple example with '--asis' for copying one keyword. But not
many. So in Commit d5542488
<http://git.savannah.gnu.org/cgit/gnuastro.git/commit/?id=d5542488> I just
added an example to use '--asis' for many keys.
Further more, I just added an implementation of that example in copy-keys.sh
<https://gitlab.com/makhlaghi/useful-scripts/-/blob/master/copy-keys.sh> (in
my Useful scripts <https://gitlab.com/makhlaghi/useful-scripts> project, for
things I haven't yet had time to implement in Gnuastro!).
But this is much easier/faster done inside the FITS program. With this task, I
am proposing to add an option like '--keytoout' for this job that is called
like below. In that command, the 'KEYA' and 'KEYB' of 'input.fits' will be
copied directly into the 'out.fits' (HDU 1).
astfits input.fits --keytoout=KEYA,KEYB --output=out.fits --outhdu=1
