117. Modern Astronomers use five principal equations in order to determine the moon's actual, from her mean, elongation (or *tithi*). These are (1) the sun's equation of the centre, (2) the moon's equation of the centre, (3) the moon's evection, (4) the moon's variation, (5) the moon's annual equation. Of these (5) is already included in the sun's equation and both are given together in Tables IX-*c* and IX-*h*, (4) depends only on the *tithi* and is given in the last column of Table XVI-A, while (2) and (3) are given respectively in Tables XVI-B and XVI-C.
