🧮 Calculation
Definition: Midpoint of the two luminaries (Cosmobiology: ☉/☽).
- Near midpoint: M = λ☉ + ((λ☽ − λ☉ + 540) mod 360 − 180) / 2, normalised to 0–360°.
- Far midpoint = M + 180°.
- Reinhold Ebertin treats ☉/☽ as the “marriage / partnership” midpoint.
Usage note: Used in Cosmobiology / Uranian midpoint trees.
