How it is worked out: the Sun, the Moon and the planets from the same ephemerides the sky map draws, for Rio de Janeiro at 22.91°S, 43.17°W, with a flat horizon and the light-pollution atlas’s estimate of its sky. Dark means the Sun 18° below the horizon; a planet counts once it is 10° up. The methods and their measured errors.
