2. Sidereal Lunar Coordinate & Navamsha D9 Equations
Using the Chitra Paksha Lahiri ayanamsha (24° 13' 40'' in November 2026), the sidereal lunar longitude λ_sid determines both the Janma Nakshatra (0..26) and the Navamsha D9 sign (0..11):
λ_sid = (λ_trop - A_Lahiri(T)) mod 360°
Nakshatra_Index = floor(λ_sid / 13.3333333333°) // 27 segments of 13°20'
Pada_Number = floor((λ_sid mod 13.3333333333°) / 3.3333333333°) + 1
Navamsha_Sign = floor(λ_sid / 3.3333333333°) mod 123. Ashtakoota 8-Factor Scoring Table (36 Gunas Maximum)
