II.4 II. VĀSIṢṬHA-SIDDHĀNTA 27 170 is left over. Deducting 119 for Tulā, 51 is left over, in Vṛścika, i.e. 51 117 of Vṛścika is gone, i.e. 30 × 51/117 degrees = 13° 5'. Therefore the true Sun = 7ʳ 13° 5'. (b) For 0 day, 0 + 6 = 6, quarter-days. 30° × 6/125 = 1° 26' gone in Meṣa. Therefore the true Sun = 0ʳ 1° 26'.

Add 1936 to the Days from Epoch, and divide the Sun by 3031. The quo- tient are called ghanas. Multiply the remainder by 9 and divide by 248. The quotient are called gatis and the remainder are called padas. 3. Divide the ghanas out by 16 and take remainder alone. Multiply this by 3, divide by 4 and take the result as rāśi etc. Subtract this from 12 rāśi and take the remainder. Add to this, minutes equal to twice the total ghanas. Add also 1ʳ 7° 29'. (The mean Moon at the end of the ghanas is got). 4. Multiply the gatis by 185, subtract a tenth of the gatis and add these also, taken as minutes. (The mean Moon at the end of the gatis is got.) If the number of padas is less than 124, they are called plus-padas. If 124 or more, 124 padas are taken and set apart as a half-gati. The remaining padas are called minus-padas. (The three technical terms here, half-gati, plus-pada and minus- pada are for use in verses 5 and
