Variables on this page (4)

json, rbe90, rli60, rli70

Purpose

OLDRAT_MOD holds the proton-capture rates of ⁶Li, ⁷Li and ⁹Be at each shell for the model at the start of the step, shared by 5 routines; the current model's rates are in NEWRAT_MOD. It replaces COMMON/OLDRAT/ (MHP via Claude, 10/14/26); JSON comes from DIMENSIONS_MOD.

What its variables hold, who sets them, who reads them. All are arrays of JSON.

RLI60, RLI70, RBE90: set by LIRATE88 when called with J = 2 (from the old model), and copied from RLI6, RLI7, RBE9 by GETW and BURSMIX at the end of a step, for the next.
Read by LIBURN and LIBURN2, which burn with the rates at both ends of the step.

Design

A blanket USE OLDRAT_MOD.

That matches COMMON's semantics. 19 MODULE OLDRAT_MOD 20C 10/20/26 MHP via Claude 21C code changed to take JSON from DIMENSIONS_MOD instead of declaring 22C a PRIVATE copy here. 23 USE DIMENSIONS_MOD 24 25 IMPLICIT NONE 26 SAVE 27 28 REAL*8 :: RLI60(JSON) 29 REAL*8 :: RLI70(JSON) 30 REAL*8 :: RBE90(JSON) 31 32 END MODULE OLDRAT_MOD
