|1||Note that the famous work by Castagnoli and Lal (1980) contains an inconsistency in the force-field formula – see details in Usoskin et al. (2005a),|
|2||The concept of VDM assumes that the geomagnetic dipole is centered at the planet’s center and its axis is aligned with the true magnetic axis.|
|3||The concept of VADM assumes that the centered geomagnetic dipole is always aligned with the geographical axis.|
|4||Isotope’s activity quantifies its decay rate and is usually given in terms of disintegrations per minute per gram of carbon.|
|5||This is not a prediction of future solar activity, but only a statistical estimate.|
