derot, json

Purpose

ROTEN_MOD holds the change of rotational kinetic energy at each shell over the step, a term of the energy equation. Shared by 3 routines. It replaces COMMON/ROTEN/ (MHP via Claude, 10/14/26); JSON comes from DIMENSIONS_MOD.

What its variables hold, who sets them, who reads them.

DEROT(JSON): $\Delta t\,(E_\mathrm{rot} - E_\mathrm{rot,old})/\Delta m$ at each shell ("7/92"), from HKEROT, HKEROTO and HS2; set by COEFFT when LROT is set, which subtracts it from the luminosity equation. Written by PUTSTORE and STITCH to the stored model.

Design

A blanket USE ROTEN_MOD in each routine.

The changes since rp_1

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

That matches COMMON's semantics. 19 MODULE ROTEN_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 :: DEROT(JSON) 29 30 END MODULE ROTEN_MOD
