Choose a Payne model:
- 4most-hr — R≈20k. 3 windows: 3926-4355, 5160-5730, 6100-6790 Å. Δλ = 0.05 Å.
- 4most-lr — R≈7k. 1 window: 3700-9450 Å. Δλ = 0.25 Å.
- 80k — R≈80k; 3 windows: 3925-6800, 7700-7800 (for O 777 line), 9050-9130 (for some C I lines) Å. Δλ = 0.05 Å. When selected, a Resolution (R) field appears—enter your spectrum's resolving power to degrade Payne to the requested resolution (slower fitting though) or leave blank.

Known issues:
- - loggf values are 0.31 dex too low for all diagnostic lines of Eu in the blue window. This means that all abundances are ~0.31 dex too high.
- - Too large files cannot be uploaded.
