What kind of text this is

Official state publication; stable.

What it contributed

greek-transmission — refinement. A Government of India committee states horoscopy was introduced in the 1st c. AD and Siddhantic astronomy blends Indian and Western conceptions from the 3rd c. BC.

The most citable transmission source in the corpus - official, modern, and by the body that produced Lahiri ayanamsa.

science-vs-convention — novel. ‘SCIENCE which nobody is permitted to violate’ versus ‘CONVENTIONS which are man-made’.

Our three-layer method, stated in 1955 by people with the authority to act on it.

practice-drifted-from-its-own-text — novel. Almanac-makers used the sidereal year where the tropical is required - contrary to the Surya-Siddhanta they cite.

Shows practice drifting from its own authority, which is a different failure from the text being wrong.

Reading the text yourself

We quote and cite; we do not republish. Most translations in this corpus are in copyright, and the public-domain ones are better served by the Internet Archive than by a copy here. Citations give chapter and verse so any claim can be checked against your own edition.

Other texts that bear on the same findings

These share a finding with this one — the same point argued, conceded or contradicted somewhere else in the corpus. Where two texts disagree, both are listed and neither is quietly dropped.
