| COMMENTS: | High-resolution spectrum: Spectral resolution in single measurements varied between 0.028 nm at 230 nm and 0.021 nm at 360 nm; in the final spectrum over the entire wavelength range the resolution is somewhat lower (∼0.04 nm) due to later data handling and manipulation Averages over 1-nm intervals of the high-resolution spectrum centered at the wavelength given in the first column Empirical fit of the temperature dependence (223-323 K): σ(λ, T) = σ(298 K) + Γ × (T - 298 K) with the temperature coefficients -------------------------------------
