Absorption cross sections calculated at 5-nm intervals using the semiempirical function
(eqn. 12)

σ(λ,T) = 2.73×10-19 cm2 × tanh0.5 × exp{-99.0 × tanh × [ln(329.5 nm/λ)]2}

    + 9.32×10-21 cm2 × tanh0.5 × exp{-91.5 × tanh × [ln(406.5 nm/λ)]2}

with tanh = tanh(hc×559.751 cm-1/2KT) = tanh(402.7/T);

λ in nm, 250 < λ < 550 nm, and T in K; 300 K > T > 195 K, derived by
