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 Java language implementation of HEALPix.
