c38.28

The planets are divided into two classes: *Inferior* (Mercury and Venus) and *Superior* (Mars, Jupiter and Saturn.) Three quantities, which we may call *a, b, v*, in the case of the inferior planets, Mercury and Venus, and *A, B, N*, in the case of the superior planets, Mars, Jupiter and Saturn, have to be determined first of all, before working out the actual geocentric longitude of any planet. Having determined these three quantities, the further procedure is the same, whether the planet is superior or inferior. We give below the calculations (1) for an inferior planet, Mercury, and (2) for a superior planet, Mars, for 202·54 days of the Solar Year A.D. 961 (i.e., 9 ghaṭikas after sunrise on 11th October A.D. 961.)
