equal distances from one another. At the part of the rim equal to the degrees
of Moon ~ Rāhu, on the eastern or western part of the orb, are the points of
first and last contacts, from which the directions can be read.
8. Multiply a fourth of the Moon's rim, (in whatever unit taken, as for e.g.
minutes or digits) by the latitude, and again by the degrees of the Moon east
or west of the meridian. Divide this by 8100. By so many units is the east or
west point of contact bent northward or away from the north respectively if
the Moon is east of the meridian, and bent away from the north and north-
ward respectively, if the Moon is west of the meridian.
The instructions to obtain the directions of the points of contact have been explained by figures
