Table 4 Model statistics of misfit between CHAOS-7 and SAC-C data

From: The CHAOS-7 geomagnetic field model and observed changes in the South Atlantic Anomaly

  SAC-C
N Mean rms
\(F_{\text {polar}}\) (nT) 26,711 0.10 3.49
\(F_{\text{non-polar}}\) (nT) 48,804 0.18 2.43
  1. Mean and rms refer to Huber-weighted mean and rms values in units of nT
