List of Footnotes
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. (2005), | |
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 | Isotope’s activity quantifies (a) in the radiometric ^{14} technique its decay rate, and is usually given in terms of disintegrations per minute per gram of carbon, and (b) in the AMS technique, the ^{14}C/^{12}C ratio, all normalized to the standard. | |
4 | This is not a prediction of future solar activity, but only a statistical estimate. |
