A companion experiment on the inelastic scattering of Ar demonstrated multi-bounce dynamics on FiberForm that were absent in the scattering from vitreous carbon. The study described here strongly suggests that the differences observed in the interactions of oxygen atoms with hot FiberForm and vitreous carbon are a result of the qualitatively different morphology of the two sp 2 carbon materials and not significant differences in their chemical reactivity. . The differences in the flux components are less than 5%. We emphasize here that the errors are likely to be much lower than 5%, as the estimates we used are highly conservative. The error decreases with shorter wavelengths and higher emissivity. Therefore, the errors in surface temperature and the TD flux are expected to be much lower. Hence, we chose not to apply the temperature correction and use the observed temperature from the pyrometer for our analysis.
