approximately.
This must be added to the position of the Sun to get
his position at the Sun-rise concerned. In the case of the
Moon the above additive constant of the Sun, is to be
multiplied by 13 13/33 because the Moon's daily motion is so
many times that of the Sun. Hence the additive constant
in the case of the Moon is x × 13 13/33 = 13 × (1 + 1/33)
where x is the additive constant in the case of the Sun.
This agrees with what Bhaskara has stated.
