Figure 6From: The BGS magnetic field candidate models for the 12th generation IGRFMean and root mean square of the residuals between parent model and input satellite data. Values for each magnetic component are calculated within within successive 30-day periods. To preserve statistical robustness, periods with fewer than 10% of mean number of data per period (approximately 3,000 for X, Y, and Z, and approximately 600 for F) are not plotted.Back to article page
