What is libhealpix-cxx2

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 dynamic library for the C++ language implementation of HEALPix. It can be used interactively via Python bindings available in a separate package. The C++ library provides input/output, basic spatial operations such as conversion between spherical coordinates and HEALPix pixels, and also sophisticated spatial operations such as querying cones or polygons, as well as upsampling/downsampling, smoothing, and fast spherical harmonic transforms.
