galot06_mod.f

GALOT06_MOD holds the grids of the low-temperature opacities of Ferguson et al. (2005), called ALEX06 in the code: $\log T$, $\log R$, $X$ and $Z$, shared by READALEX06, GETALEX06 and ALEX06TAB. It replaces COMMON/GALOT06/ (MHP via Claude, 10/14/26). The table dimensions NUMD = 19, NUMT = 85, NUMX = 9, NUMZ = 16 are PRIVATE, since other tables use the same names with other values.

What its variables hold, who sets them, who reads them. All four carry initial values, moved from the DATA statements of READALEX06; nothing changes them at run time.

• TGR06(NUMT): $\log T$ from 2.70 to 4.50 (steps of 0.05, 0.01 between 2.90 and 3.50, then 0.05).
• R0GR06(NUMD): $\log R$ from −8 to 1 in steps of 0.5.
• XXG06(NUMX): the nine $X$ values, 0 to 1; ZZG06(NUMZ): the sixteen $Z$ values, 0 to 0.10.
• READALEX06 checks the headers of the tables it reads against them (on a mismatch it stops the run, except for the $X$, $Z$ check of its first loop, which prints "run stopped" but whose STOP is commented out: readalex06.f, suspected bug 1); GETALEX06 locates $\log T$ and $\log R$ in them for the interpolation; ALEX06TAB locates $X$ and $Z$.

A blanket USE GALOT06_MOD. The literals are copied verbatim, so their stored values are those of the DATA statements. The module's header says they came from PARMIN's DATA statements and are namelist variables; at rp_1 they were in READALEX06, and they are in no namelist (a comment copied from the other conversions).
