  1. M-1 and M-2 are IZMIRAN models based on Kosmos-49 and Kosmos-321 data, respectively (Dolginov et al. 1967, 1976) (discussed in Sections “Verification of historic models of the geomagnetic field”, “Comparison of the model predictions with observatory data”); N-1 and N-2 are the models proposed in this research (discussed in Sections “A new geomagnetic field model based on satellite data”, “Comparison of the model predictions with observatory data”).
