*Calulate the angular separation between two locations on the sky*

        Input precision should be respected.

        **Key Arguments:**

        **Return:**
            - ``angularSeparation`` -- total angular separation between coordinates (arcsec)
            - ``north`` -- north-south separation between coordinates (arcsec)
            - ``east`` -- east-west separation between coordinates (arcsec)

        See main class usage for details.
