This page provides ASCII listings of Geotail MGF magnetic field, EFD electric field, and LEP ion moment data for any available intervals through interactive forms.
GSM: X to the sun; X-Z plane contains the Earth's dipole axis.
GSE: X to the sun; Z along the ecliptic pole.
SM : Z along the Earth's dipole; X-Z plane contains the sun direction.
The Y axis completes the right-handed coordinate system, Y=Z x X (duskward).
SC : The satellite coordinate system. Z along the satellite spin axis; X-Z plane contains the sun direction. The Y axis completes the right-handed coordinate system, Y=Z x X (duskward). The SC system is nearly equal to GSE since the satellite spin axis is almost perpendicular to the ecliptic plane.
The Geotail satellite has two editors onboard: The Editor-A data are only acquired with the real-time operation in Usuda Deep Space Center (UDSC) or Uchinoura Space Center (USC), Japan, while the Editor-B data are continuously recorded in the onboard tape recorders for 24 hours and are dumped to the NASA JPL Deep Space Network (DSN) stations.
