w was an important angle in the Munjala Model and the solution to the problem of a difference of 2.5 degrees in the lunar longitude had to be solved. So Munjala brought in an angle, w, angle between the Mean Sun and the Moon’s Apogee.
The angle n is the elongation of the Sun from the Mean Moon and so the
Manda Anomaly, Alpha = w + n
