Divide this by the tabular cosine of the latitude at the particular moment and the quotient is to be divided again by the tabular radius (\*vyāsadala\*). The result (will give the correction for longitude which) is to be added to or subtracted from the moon’s longitude, as the moon-minus-node is in an even or an odd quadrant, respectively. The True Moon measured on the ecliptic is thus got’.³ - [Previous: c8.s2.5](https://indike.org/pramana/ins.science.sarma-1972.c8.s2.5) - [Next: c8.s2.7](https://indike.org/pramana/ins.science.sarma-1972.c8.s2.7) - [Up: c8.s2](https://indike.org/pramana/ins.science.sarma-1972.c8.s2) --- Source: [https://indike.org/pramana/ins.science.sarma-1972.c8.s2.6](https://indike.org/pramana/ins.science.sarma-1972.c8.s2.6) · Pramāṇa
