Fig. 4From: Evidence-based uncertainty estimates for the International Geomagnetic Reference FieldResiduals plotted against quasi-dipole latitude (gray dots) for a North (X), b East (Y), and c vertical (Z) field. The residuals are divided into bins of 2.5\(^\circ\) latitude and the 68.3, 95.4 and 99.7% confidence intervals are computed (colored bars)Back to article page
