Great — I’ll run option A using high-precision refractive-index data and the spectral set you suggested. Quick confirmation so I run exactly what you want:

I plan to use:
* refractive-index data for liquid water (20 °C) from a high-quality source (refractiveindex.info / Hale & Querry),
* a Planck continuum at T = 5800 K (Sun-like) as the main weight, and
* narrow emission lines: Hα (656.28 nm), Hβ (486.13 nm), Na D (≈589.0 nm), [O III] (500.7 nm), plus one representative plasma/nebular line to include a plasma example (I suggest [N II] 658.3 nm or I can use He II 468.6 nm or Fe XIV 530.3 nm if you prefer).

Please confirm which plasma/extra line you want (pick one of the three above), and I’ll start the run. Once you confirm I will:
# fetch the refractive-index table and interpolate n(λ) across 350–900 nm (visible band),
# compute the primary-rainbow deviation angle D_min(λ) via geometric-optics ray tracing for a spherical droplet,
# compute weighted means for Planck(5800 K) alone and Planck+lines (with narrow Gaussians for the lines),
# return numeric results, plots (D_min vs λ and the weighted spectrum), and a brief interpretation.

Ready to run — which plasma line shall I include: [N II] 658.3 nm, He II 468.6 nm, or Fe XIV 530.3 nm?
