Fig. 4
Top: residuals \(\Delta B_C = B_C - B_{C, \text {mod}}\) in dependence on QD-latitude for the 2 days 3 to 4 April 2011, for FGM1. Blue dots present results when discarding “common calibration parameters” (i.e. not accounting for spacecraft disturbance fields and magnetometer non-linearities—case #6 of Table 1) while red dots present results for the fully calibrated data (case #1). Bottom: magnetorquer currents in dependence on QD-latitude for the same data span.
