S2 PACKAGE Object oriented wrapper for functions on the sphere --------------------------------------------------------------- DESCRIPTION The s2 package contains functionality to support functions defined on the sky/sphere and was developed primarily for astrophysical applications. Both real space map and harmonic space spherical harmonic representations are supported. Basic sky representations have been extended to simulate full sky noise distributions and Gaussian cosmic microwave background realisations. Support for the representation and convolution of beams is also provided. A HEALPix spherical pixelisation scheme is adopted, although this may be extended in the future to support other pixelisations of the sphere. VERSION Release 1.1 AUTHORS J. D. McEwen (http://www.jasonmcewen.org) ACKNOWLEDGEMENTS D. J. Mortlock S. M. Feeney REFERENCE The s2 package was written originally for the development of fast continuous wavelet transform algorithms on the sphere but has since evolved to provide much additional functionality.
