Parameter #3

Name: Electron Density

ParameterKey: E_DENS

Description

Electron number density.

Caveats: Per Lynn Wilson Jan2015: These results cannot take the spacecraft potential into account. Wind does not measure the spacecraft potential actively, so it cannot perform this correction onboard and the results have many uncertainties.

Parameter #5

Name: Residual Electron Velocity Variance

ParameterKey: E_TENS

Description

Residual Variance in Electron Velocity (6 components in instrument coords)

Caveats: Per Lynn Wilson Jan2015: This is in one of two units. It is calculated as the pressure tensor divided by the number density. In the decommutation source code, they say the units are (km/s)^2. In some of the other moment analysis software, the pressure is in units of [eV cm^(-3)].

Parameter #7

Name: Electron Heat Flux

ParameterKey: E_Q

Description

Electron Heat Flux (Q)

Caveats: Per Lynn Wilson Jan2015: This is the vector form of the electron heat flux. It should have units of either [(km/s)^3 cm^(-3)] or [eV km/s cm^(-3)] . I am guessing the former due to the .VV units used above, since this is usually given the structure tag .NVVV.

Units: (km/s)^3/cm^3
