            <AlternateName>STEREO PLASTIC proton parameters from 1D Maxwellian fits</AlternateName>

            <Description>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.
