FastCSWT PACKAGE A fast directional continuous wavelet transform on the sphere --------------------------------------------------------------- DESCRIPTION This package provides functionality to perform a directional continuous wavelet transform on the sphere. The transform is based on the construction of the continuous spherical wavelet transform (CSWT) developed by Antoine and Vanderghynest 1999. A fast implementation of the CSWT (based on the fast spherical convolution developed by Wandelt and Gorski 2001) is also provided. The fast algorithm in the context of the CSWT, and as implemented in this package, is described in our related paper: McEwen et al. 2007. VERSION Release 1.0, 1 July 2008 AUTHORS J. D.
