Comments: The high-resolution absorption cross-section measurements of O2 in the 108.0 to 108.7 nm spectral region have been carried 
out with a resolution of 0.0008 nm and at temperatures of 295 and 535 K. The absorption features in this spectral region exhibit primarily a 
blue-shaded broad band with a band head peaked at 108.52 nm. As the temperature increases from 295 to 535 K, we observe a decrease 
in cross-section values by as much as 30% over the contour of the diffuse band. Similarly, the cross-section values of the sharp features 
decrease as temperature increases.
