Abstract

CDS Strasbourg is hosting a 2-day workshop on Python code and libraries for HEALPix.

HEALPix is a pixelisation of the sky that is used more and more in astronomy. There are multiple Python packages that provide HEALPix functionality (especially astropy-healpix and healpy) or use HEALPix (e.g. reproject, MOCPy, hips, Gammapy).

The goal of the workshop is to bring together HEALPix experts and Python developers to exchange knowledge, and to discuss plans and continue work on the packages mentioned above, or other Python codes on HEALPix.

Everyone is welcome. If this is of interest to you or you have any questions, please get in contact!
