Oxygen: the fitted model

The oxygen model (fit/O2): effective oscillators fitted to Smith, Huber & Parkinson’s ultraviolet above the Schumann-Runge bands, Egan et al.’s 2026 values at 633 and 1542 nm, Birch at 633 nm, Hohm’s 325-633 nm dispersion, Swift and Marchetti; Zhang’s 800 nm value (A band) and Kumar & Thakkar’s sums are validators.
