=== You earlier asked specifically to “Run now with an approximate analytic dispersion model for water. The spectral lines and temperatures you suggested.” — I have just done that run. ===

If you want me to run the improved, more accurate test I recommend these inputs:
* Confirm: do you want the water/rainbow geometry test first (yes/no)?
* Choose spectra to try precisely: e.g. - Planck at 5800 K (Sun) — yes/no - Planck at 3000 K — yes/no - Real solar spectrum (observed) — yes/no - Atomic lines: Hα, Hβ, Na D — yes/no - Plasma set: O III 500.7 nm / He II 468.6 nm — yes/no
* Allow me to use high-precision refractive index data (I can fetch refractiveindex.info if you want — say “yes, fetch r.i. data” and I’ll do a web lookup).

If you prefer, I can proceed step-by-step: first replace the approximate dispersion with precise n(λ) (no other changes). That will already tell us how far the rough model was from reality.

Say which option you prefer and I’ll continue.
