Description [src]
Considering a spherical coordinate system where the halo is at the north pole, this
function calculates the polar and azimuthal angles of a point in the sky. That is,
$\theta$ = theta provides the angular separation from the halo to the point in the
sky, and $\phi$ = phi provides the azimuthal angle.
