VIII.6 VIII. ROMAKA-SIDDHĀNTA — SOLAR ECLIPSE 183 of the intervals as the maximum equation of the centre, and neglecting the correction of the epicycle, we give hereunder the given and computed values for comparison. Anomaly 15° 30° 45° 60° 75° 90° Computed intervals 37′ 6″ 34′ 36″ 29′ 42″ 22′ 46″ 14′ 20″ 4′ 53″ Given intervals 34′ 42″ 33′ 55″ 30′ 2″ 24′ 10″ 14′ 16″ 6′ 18″ The sum forming the maximum is 143′ 23″, and very near that of the Pauliśa, and very much more than the actual. This excessive roughness itself is an indication that the Siddhānta is not indigenous. The author has not clearly mentioned where the intervals are to be taken in the given order and where in the reverse order, as also where they are additive and where subtractive. Or, adopting the reading mithunadalāt, we can understand that the equation of the centre is subtractive in the six signs of the mean Sun beginning from the middle of Gemini, and therefore additive in the other six. From the corrected reading, vyutkramaśasca, we understand that after taking the inter- vals in the given order, we take them in the reverse order. From these everything else is inferred.

The mean Moon in revolutions etc. is got by multiplying the 'day' by 38100, subtracting 10,984, and dividing by 10,40,953. 5. The mean anomaly in revolutions etc. is obtained by multiplying the days by 110, adding 609, and dividing by 3031, the result being for sunset at Ujjain. 6. For the half-signs of anomaly the intervals of equation of the centre are: 1° + 14′ + 25″, 1° + 11′ + 48″, 1° + 2′ − 9″, 48′ − 15″, 48′ − 18″ − 0″, and 48′ − 18′ − 20′ −·1″ (i.e. (1) 1° 14′ 25″, (2) 1° 11′ 48″, (3) 1° 1′ 51″, (4) 47′ 45″, (5) 30′ 0″, (6) 9′ 59″). 4a.
