The magnetic moment of the Earth is a vector opposite to the unit vector carrying the ZSM axis (SM: Solar Magnetic reference frame). The tilt angle is the angle between the ZSM (the opposite of the Earth magnetic moment) and ZGSM directions. The roll angle is the angle between the projection of the Earth magnetic moment on the YZGSE plane and the ZGSE direction. It is also the angle between the XZGSM and the XZGSE planes or the XYGSM and XYGSE planes. Earth dipole tilt and roll angles are calculated with the use of GEOPACK-2008 package.
