About

The reproject package is a Python package to reproject astronomical images and cubes using various techniques via a uniform interface. By reprojection, we mean the re-gridding of data from one world coordinate system to another (for example changing the pixel resolution, orientation, coordinate system). Currently, we have implemented reprojection by interpolation (like SWARP <http://www.astromatic.net/software/swarp>), by the adaptive and anti-aliased algorithm of DeForest (2004) <https://doi.org/10.1023/B:SOLA.0000021743.24248.b0>_, and by finding the exact overlap between pixels on the celestial sphere (like Montage <http://montage.ipac.caltech.edu/index.html>). It can also reproject to/from HEALPIX projections by relying on the astropy-healpix <https://github.com/astropy/astropy-healpix>__ package.
