Wind Solar Wind Experiment (SWE) Electron Quadrature Moments Parameters (12-15s rate) (New Mode)

We compensate for the limited nature of our observations under this instrument mode by combining electron observations with bulk-velocity estimates derived from corresponding ion observations. The (13) energy channels over which observations are made are: E = 19.34, 38.68, 58.03, 77.37, 96.71, 116.1, 193.4, 290.1, 425.5, 580.3, 773.7, 1006., and 1238. eV; f(E,Az,El) [#/{cc*(cm/s)^3}] being obtained for each E, using an 8x6 grid of look-directions (Azimuth x Elevation, with ~45x9 deg. "pixels")--thus constituting an 'electron distribution'.

A fitted Maxwellian model supplements the "core" regime of each distribution. N_elec [#/cc] gives the density value derived for the full distribution, while NcElec [#/cc] gives that of the core. U_eGSE and UceGSE [km/s, GSE], resp. supply the full and core bulk-velocity.

P_eGSE [erg/cc, GSE] has the [Pxx, Pxy, Pxz, Pyy, Pyz, Pzz] components of the derived pressure-tensor. T_elec and TcElec [K], resp. provide the full and core total-temperatures; W_elec and WcElec [eV] specifying the corresponding thermal-energies. Te_pal, Te_per, TecPal and TecPer [K] give resp. full and core parallel- and perpendicular-temperatures (wrt B), with Te_ani and TecAni [unitless] furnishing the perpendicular/parallel temperature-anisotropies for each regime.

Finally, Gyrtrp [unitless] indicates the derived electron gyrotropy. The data set reported here contains: N_elec, NcElec, U_eGSE, UceGSE, P_eGSE, T_elec, TcElec, W_elec, WcElec, Te_pal, Te_per, TecPal, TecPer, Te_ani, TecAni, and Gyrtrp (as described above).
