HEALPix is an acronym for Hierarchical Equal Area isoLatitude
Pixelization of a sphere. As suggested in the name, this pixelization
produces a subdivision of a spherical surface in which each pixel
covers the same surface area as every other pixel. It is commonly
used to store all-sky astronomical images, most famously maps of the
cosmic microwave background.
