Reproject healpix FITS images.

Project description

unhealpix

Regrid a HEALPIX FITS file to target FITS image.

Description

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!

Getting Started

Dependencies

Required libraries:

Installing

  • Simply clone to wherever you'd prefer

Executing program

Example usage:

python unhealpix.py healpix.fits target.fits output.fits

Output will be a FITS file with the shape of target.fits

Notes

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.
