Examples of vect2pix_nest()

gov.fnal.eag.healpix.PixTools.vect2pix_nest()
renders the pixel number pix (NESTED scheme) for a pixel which contains a point on a sphere at coordinate vector (x,y,z), given the map resolution parameter nside. The computation is made to the highest resolution available (nside=ns_max) and then degraded to that requared (by Integer division) this doesn't cost much, and it makes sure that the treatment of round-off will be consistent for every resolution @param nside long the map resolution @param vector Vewctor3d the input vector @return pixel long @throws IllegalArgumentException
