Python version: comp2_mod.py, 11 lines, on the right (switch to Python above the code).

Variables on this page (2)

y3env, yenv

Purpose

COMP2_MOD holds the envelope's helium: YENV (⁴He, $1 - X - Z - Y_3$) and Y3ENV (³He). It replaces COMMON/COMP2/ (MHP via Claude, 10/14/26); it completes COMP_MOD.

Who sets them, who reads them. STARIN sets both from the surface composition; PHYSIC and CHECKC read them.

Changed since rp_1. New file: COMMON/COMP2/ as a module.
