Comments: Near-infrared absorption cross sections and integrated absorption intensities of gas phase oxygen and nitrogen mixtures have 
been determined from laboratory measurements. Spectra were recorded at instrument resolutions of 0.5 and 0.05 cm-1, between 2200-12500 cm-1 
(between 4.5 and 0.8 µm).
