2160 238900 •009 This table shows that, although the values of the diameters and mean distances of the Sun and the Moon given by different authorities differ, their ratios are practically the same. It may be pointed out that it is these ratios and not the diameters or distances that are used in the calculation of the eclipses-a fact which is partly responsible for the great accuracy attained by Hindu astronomers in the prediction of the eclipses. diameters of the Sun and the
5. The diameters of the Sun and the Moon when (seve- rally) multiplied by the radius and divided by their true distances in yojanas become the (angular) diameters in minutes.¹ 1 This rule is found also in BrSpSi, xxi. 34(ii) ; ŚiDVṛ, I, iv, 8; Siśe, v. 6; and SiSi I, v .7.
