Fig. 2From: In-flight scalar calibration and characterisation of the Swarm magnetometry packageUncorrected scalar residuals between ASM and VFM magnetometers, \(\Delta F\), plotted versus Sun incident angles \(\alpha\) and \(\beta\). The \(\beta\) angle oscillates slowly in time; hence, the un-folded \(\beta\) angle corresponds to season which is indicated in blue on the right-hand side. Local time of the ascending node is shown in red (axis on top)Back to article page
