Comments: Photoabsorption cross sections have been measured for carbon dioxide at 0.5 Å intervals between 1200 and 1970 Å.
The room temperature cross sections are found to be in good agreement with previous measurements and a temperature effect is 
found which is small at the shorter wavelengths, passing through a minimum near 1400 Å. At longer wavelengths the temperature 
effect increases steadily until at some fixed wavelengths above 1900 A the cross section increases by a factor of about 20 as the 
temperature is increased from 200 to 370 K.
