Regrid a HEALPIX FITS file to target FITS image.
A simple implementation of Astropy and Reproject FITS handling. This script reprojects a HEALPIX projected FITS file to an image projection. Beware of any projection issues this may cause!
Required libraries:
- Simply clone to wherever you'd prefer
Example usage:
python unhealpix.py healpix.fits target.fits output.fits
Output will be a FITS file with the shape of target.fits
Currently the output is forced to be an image (NAXIS = 2). Modifcations will need to be made to handle FITS cubes (e.g. NAXIS = 3). In addition, the output header is rather minimal, so refer to the original file's header for full details.
