FLINTS

Overall presentation

FLINTS is an interpolation algorithm of fields sampled on a sphere. We assumed originally that the field corresponds to a band limited Gaussian random field but it is also optimal in the least-square sense for any field on the sphere.

We propose here a C++/OpenMP implementation of this algorithm. It uses the specificities of HEALPix pixelization for speed optimization. The code is mostly self-documenting through comments.
