Abstract

When the planet lies at the mid-point of the visible half [of the ecliptic] then there will be no parallax in longitude (lambana). [Then] it is also in the dṙkkṣepa-lagna. Parallax in longitude is possible only when the planet is to the east or west of this (dṙkkṣepa-lagna).

When the planet lies on the ecliptic that also happens to be a vertical circle (samordhvagaapavṙtta), then there will be no parallax in latitude (nati) also. It is possible to have parallax in latitude only when the planet is displaced from the centre of the prime vertical (zenith) and lies in the kṣepakoṭivṙtta which is secondary to the ecliptic.
