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.
.
This package provides the static library and headers for the C language
implementation of HEALPix. The C library provides basic input/output of
HEALPix maps as well as basic spatial operations like conversion between
spherical coordinates and HEALPix pixels.
