# (actually energy, but in plasma physics we just call it temperature :-)

On the plot of cross section vs T, I always understood that the plots which show energy are "per-particle", whereas the plots which show temperature are integrated over a Maxwell-Boltzmann distribution -- this also leads to a reduction in the peak T/E for the DT distribution thanks to the Maxwell tail.

The comment on L179 of the script seems to suggest that T vs E is just taking temperature vs energy, presumably just considering E = E_thermal for a distribution?

Anyway, the long and short of my question is: Is it just sigma(energy), scaled by 1/1.1e4 to translate between energy (eV) and temperature (K), or are thermal distributions taken into account?
