fitsglue - catenate fits images into a fitscube
fitsglue catenates a number of fits files (usually planes) together
in a fits cube. It only works for FITS primary header images. It also had
rudimentary options to attempt to fix up the WCS of the new fits cube.
you need to catenate the images in the spatial (1st or 2nd dimension) plane,
The following parameters are recognized in
any order if the keyword is also given:
Catenating three fitsfiles
map001.fits, map002.fits and map003.fits can be done in two ways:
- Input fits files. No default.
- Output fits file.
- Check for multiple fits files on input?
- Preset NAXIS3 here, or let program scan first. Setting
this parameter to 0 will cause it to scan the files first. Default: 0
- Compact (move) dummy axes to the end Default: f
- Optional list
of integers, which if properly used with a template filename in in= can
be used to process a large number of input files. This is needed if the
shell doesn’t allow you to build large strings that may be needed to pass
to in=. Default: not used.
- Attempt to add a more decent WCS (first
FITS file) to the output cube Default: f.
% fitsglue in=map001.fits,map002.fits,map003.fits out=cube.fits
% fitsglue in=map%03d.fits out=cube.fits inlist=1:3
where the compact second form can be useful if the string length becomes
too long for a shell to handle, or too impractical to type. Notice that
the in= keyword does not directly support the usual unix wildcard, although
an extra pass with sed may be used:
% set in=‘echo map*.fits | sed ’s/ /,/g’‘
% fitsglue in=$in out=cube.fits
You can also use NEMO’s macro substitution (see also getparam(3NEMO)
% ls map*.fits > input_files
% fitsglue in=@input_file out=cube.fits
