List of pix2ang_nest() Examples

Examples of pix2ang_nest()

gov.fnal.eag.healpix.PixTools.pix2ang_nest()
Renders theta and phi coordinates of the normal pixel center for the pixel number ipix (NESTED scheme) given the map resolution parameter nside. @param nside map resolution parameter - long @param ipix long pixel number @return double[] (theta, phi) @throws IllegalArgumentException
