rcosmo: Cosmic Microwave Background Data Analysis
Tools for handling and analysing spherical data on a HEALPix grid,
with applications to cosmic microwave background maps. Supports reading FITS
files, converting between spherical and Cartesian coordinates and HEALPix
ordering schemes, selecting sky regions, sampling pixels, and visualising
maps. Implements empirical covariance, correlation and variogram estimation,
covariance model fitting, angular power spectrum estimation, and
distributional and entropy-based comparisons of spherical data. The package
and its methods are described by Fryer, Li and Olenko (2020)
