Top Difference maps of \(B_r\) at Earth’s surface between SIFMplus and MF7 (left) and \(\hbox {SIFM}_x\) and MF7 (right), respectively. Bottom left Difference maps between SIFMplus and \(\hbox {SIFMplus}_{{\text {noMLT}}}\) (left). Bottom right \(B_r\) of SIFMplus. All maps are evaluated for degrees n = 16–75. Red lines locate the dip-equator (\(0^\circ \) QD latitude) and \(\pm 55^\circ \) iso-QD latitudes. Note the various scales
