Comments: Laboratory measurements of the relative absorption cross sections of CO2 at the temperatures 195 and 295 K have been 
made throughout the wavelength region 118.7-175.5 nm. Laboratory measurements of the absolute absorption cross sections of CO2 
at the temperature 195 and 295 K have been made at 12 different wavelengths in the region 118.7-175.5 nm. These absolute values 
have been used to put the relative cross section measurements of CO2 at 195 and 295 K on an absolute basis throughout the region 
118.7-175.5 nm. Almost no temperature dependence was observed in the peak cross sections of the strong bands at 130 nm region, 
but large temperature effects are seen in the other regions.
