| Definition: |
Eccentric Dipole (ECD) coordinate system thataligns with a dipole whose origin and orientation may be different from thephysical center and spin axis of the containing body. The IGRF-12coefficients for 2015 are used to determine the origin for the earth. The2015 positions are North dip pole: latitude: 86.29, longitude -160.06. Southdip pole latitide: -64.28, longitude: 136.59, North geometric pole latitude:80.37, longitude: -72.63, South geomagnetic pole latitude: -80.37,longitude: 107.37ECD is defined in doi:10.1186/s40623-015-0228-9. |
