Short summary

This study statistically quantifies the errors in local magnetic field directions that are derived from electron directional distributions measured by Los Alamos National Laboratory geosynchronous (LANL GEO) satellites. We demonstrate for the first time that derived magnetic field directions in GEO orbit should statistically match the real magnetic directions ~2 times better than those from a list of empirical models and have no significant dependence on magnetospheric activities.
