List of Nside2Npix() Examples

Examples of Nside2Npix()

gov.fnal.eag.healpix.PixTools.Nside2Npix()
calculates npix such that npix = 12*nside^2 nside should be a power of 2, and smaller than ns_max otherwise return -1 @param nside long the map resolution @return npix long the number of pixels in the map
