The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Relations using Te([N II]) show lower dispersions, indicating that this diagnostic provides a more reliable estimate of the low-ionisation zone temperature when only higher-ionisation Te diagnostics are available.

C2weakest assumption

That the 699 spectra with multiple Te diagnostics form a representative sample and that recomputed values with updated atomic data accurately reflect true temperatures without introducing new systematic offsets.

C3one line summary

Large-sample analysis finds Te([N II]) relations have lower dispersion than those for [O II] or [S II], making it a more reliable low-ionization temperature proxy.
