      "Caveats": "The CPI solar wind ion analyzer is an E/Q analyzer and the initial distribution functions were calculated assuming that the plasma is H+. 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.",
