Figure 1

Residuals of the least-squares fit to ASM data. Black dots: residual differences between ASM data and the magnetic field strength calculated from VFM data for the set of calibration parameters given in Table 1. The model does not include a Sun position dependence of the offsets. Red line: estimated local time for data points selected within 1° of the equator when the satellite is flying North.
