Genesis interplanetary field orientation proxy

ResourceID
spase://NASA/NumericalData/Genesis/GIM/B-Proxy/PT160S

Description
The vector direction of peak suprathermal electron flux as measured with the Genesis Electron Monitor (GEM) instrument. This direction serves as a proxy for the interplanetary field orientation. The suprathermal electron flux is either parallel or anti-parallel to the interplanetary magnetic field. The true field polarity (+ or -) cannot be determined from GEM. Angles are given in Geocentric Solar Ecliptic (GSE) coordinates.
