COMMENTS: Presumably averages over 1-nm intervals of the absorption spectrum measured at a spectral resolution of 0.19 nm

The absorption cross sections and their error limits (third column of the datafile) are taken from the "Supplementary Material" published along with the online version of the article

Selected vaues for 5-nm intervals are listed in Table 1 of the paper

Absorption measurements at temperatures between 273 and 305 K have shown the cross sections to be independent of temperature within the error limits
