2.3.1 spase://CNES/NumericalData/CDPP-AMDA/STEREO-A/PLASTIC/sta-l2-pla proton 1D fit STEREO PLASTIC proton parameters from 1D Maxwellian fits 2015-10-14T14:35:29Z Data from ftp://stereoftp.nascom.nasa.gov. PLASTIC has a ~1 minute energy per charge (E/Q) cadence in which the electrostatic analyzer (ESA) steps through 128 logarithmically spaced E/Q steps from ~80 keV/e, down to ~0.3 keV/e. Proton bulk parameters provided here (speed, density, thermal) are derived from a 1D Maxwellian fit to a single detector rate (no coincidence required), and are corrected for background and dead time. The N/S angle is derived from a peak fitting to the N/S (deflection) rate bins of the same rate. The E/W angle is derived from a separate double coincidence rate. The proton velocity components are corrected for spacecraft aberration and are derived using the N/S and E/W angles. Please acknowledge STEREO PLASTIC Investigation (A.B.
