S2FIL PACKAGE Optimal filtering on the sphere --------------------------------------------------------------- DESCRIPTION This package provides functionality to support optimal filtering on the sphere. Optimal directional matched filters (MF) and scale adaptive filters (SAF) may be constructed from a template and stochastic background process. Functionality is incorporated also to filter a sky data map using an optimal filter and to detect compact objects using a naive thresholding strategy. VERSION Release 1.1 AUTHORS J. D.
