Table 6 CM6 weighted residual statistics for Swarm Alpha and Bravo, where “QD” denotes Quasi-Dipole, “NS” denotes North–South along-track, “DF/SF” denotes scalar differences and sums, respectively, “DN/SN”, “DE/SE”, and “DC/SC” denote vector differences and sums in the local North-East-Center frame, respectively, “F” denotes scalar, and “B”, “P”, and “3” denote vector measurements in the HB-theory frame, respectively

From: CM6: a comprehensive geomagnetic field model derived from both CHAMP and Swarm satellite observations
