The data set provides the relative differential energy flux (J*E) of He+ in 4 ranges of V/Vsw (8.00 to 3.50; 3.50 to 2.50; 2.50 to 1.85; and 1.85 to 1.44). The identification of He+ is based on the measurement of energy per charge (E/q), time-of-flight (TOF), and total energy (SSD) of ions with the PLASTIC sensor. These data include double (E/Q, TOF) and triple coincidences ((E/Q, TOF, SSD) (see e.g. Galvin et al., Space Sci. Rev. 136, p 437-468, 2008). The proton bulk parameters Vsw (km/s), Vtherm (km/s) and Density (Np in 1/cc), also provided in this file, are derived from a 1D Maxwellian fit to a single detector rate (no coincidence required), and are corrected for background and dead time. The software version number used to derive the proton bulk parameters is shown in the file header (c.f. section on File Format). The most recent update of the proton bulk parameters can be found on the following STEREO website: http://stereo-ssc.nascom.nasa.gov/data/ins_data/plastic/level2/Protons/ For a full explanation, see the description at http://stereo-ssc.nascom.nasa.gov/data/ins_data/plastic/level3/HePlus/READ_ME_PLASTIC_HePlus_Fluxes.pdf Please acknowledge STEREO PLASTIC Investigation (A.B.
