1. Calculation engine
TKS Ephemeris — apparent positions from JPL DE441 (Chebyshev kernels), no external ephemeris library; the same engine drives Pañcāṅga, Jyotiṣa, eclipses and the astronomy pages.Date range — −13000 … +17000 with an Enterprise key (default 1950–2050 open); proleptic Gregorian/Julian handling.ΔT — SMH2016 model; long-range Vondrák precession; true obliquity and nutation (IAU 2006/2000B).True and mean node — osculating Rāhu/Ketu by default (node=mean for the mean node); topocentric Moon option.Ayanāṃśa choices (4) — TKS true Chitrāpakṣa (default), KP, Lahiri (ICRC-1956, true), and Tropical (sāyana, none).Engine B / TKS-OWN — independent N-body ephemeris (1900–2100 file) as a cross-check; not the production source.Verification — cross-checks against PyJHora (Pañcāṅga, Aṣṭakavarga, Ārūḍha, Tājika); oracles and range audit in docs/tks-range-audit.md.2.
