HealPixProjection is a project to allow easy and efficient projection of healpix maps onto planar grids. It can be used as a standalone program cutsky
$ cutsky 0.0 0.0 --mapfilenames HFI_SkyMap_857_2048_R2.00_full.fitsor as a python function
from hpproj import cutsky
result = cutsky([0.0, 0.0], maps={'Planck 857': {'filename': 'HFI_SkyMap_857_2048_R2.00_full.fits'}} )or as a python class, for optimization when producting several cuts
from hpproj import CutSky, to_coord
cutsky = CutSky({'Planck 857': {'filename': 'HFI_SkyMap_857_2048_R2.00_full.fits'}})
result = cutsky.cut_fits(to_coord([0., 0.])Features
Galactic and equatorial system supported
All projection system from wcslib
Project several healpix maps at once, efficiently !
Output in fits, png or votable for the central point source photometry
