Care must be taken when multi-component plasmas are present. If He++ is present and is flowing with the same speed as the H+ component, it will contribute to the distribution function at twice the velocity (four times the energy) of the H+. To facilitate the automated processing of the data the integral was evaluated between vmin = 171 km/s and vmax = 1.35 × u . The resulting temperatures produce excellent fits to the observations. When He++ is present the distribution functions are consistent with an He++ temperature, THe++ = 4 × TH+, i.e., the H+ and He++ have similar thermal velocities.
