EPIGRAPHIA INDICA.
[VOL. XVII.
equal-space system of division of the ecliptic, which ended when "n" =33333; but that by the system of Garga or the Brahma-Siddhanta (our present authority) she was in Magha, of which the ending points are respectively 35185 and 3477-1. Converted into degrees (Table VIII-B, Indian Calendar, or Table XLV-B, above) the moon at that mean sunrise stood at about 119°51'.
For the value of "n" at any later hour of the given day the index-value for the time since mean sunrise must be added (Table LXXXI) to the "n" of mean sunrise. At about 3 hours 50 min. after mean sunrise, for instance, the mean moon entered, Magha by the equal-space system; for the beginning point of that nakshatra is 3333-3. The increase of "n" in 3 hours 50 min. is 4.3728, and 3328-9730+4-3728-3333-3458.
Example 6. To find the yoga, "y", at the same moment as in Example 5.
The formula for finding the yoga-index is either s+n="y", the yoga-index; or, in cases where it is not necessary to calculate n (the nakshatra), 2 "s"+a="y". Here, at mean sunrise on 14 June A.D. 625, we have found ""-2328-8118 and "n"=3328-9730. The yoga-index, "y", therefore, =5657-7848; and reference to Table VIII, Indian Calendar, cols. 12-13, or Table LXVIII (above, Vol. XVI, cols. 6, 8, 9, 10), shews that the mean moon was at that moment in the yoga Siddhi. Again 2 sm4657-6236, and this +"a," which was found to be 1000-16125657-7848, the same as before.
