127 The bhujantara correction is, as stated before, the correction for the equation of time due to the eccentricity of the ecliptic. An approximate formula for finding the Rsine of the Sun's declination: 25. The Rsine of the Sun's longitude corrected for the three corrections (viz. desantara, bahuphala, and bhujantara), as multiplied by 13 and divided by 32, is (the Rsine of) the Sun's declination. The remaining determinations (such as the calculation of the day-radius, etc.) should be made as before. CORRECTION UE TO SUN'S ASCENSIONAL DIFFERENCE From iii. 6-7, we have (1) Rsin & 1397 x Rsin > 3438 where and are the Sun's sayana longitude and declination respec- tively. giving Now 1397 3438 - 1 1 1 1. 1 1 1 2 + 2+5+1+9+1+9⁹ 1 2 11 13 2' 5'27' 32 as the successive approximations of 9 Writing for 1397 3438 13 its fourth approximation 32 (1) reduces to , Rsin S 1 13 x Rsin > 32 1397 3438 which is the formula stated in the text. A rule relating to the determination and application of the correction due to the ascensional difference of the Sun (called cara-samskara or cara correction): 26-27. The (mean) daily motion (of the Sun) multiplied by the asus of the (Sun's) ascensional difference and divided by the number of asus in a day and night (i.e., by 21600) should be subtracted from or added to the (Sun's) longitude computed for sunrise or sunset respectively, provided that the Sun is in the]
