Lowes–Mauersberger spectral comparison of models. Spectra of the official DGRF 2015.0 model (heavy black line) and of its difference with, respectively, the DGRF 2015.0 candidate model (green line) and IGRF 2015.0 candidate model of Vigneron et al. (2015) (red line). Also shown, spectra of the difference between the DGRF 2015.0 candidate model and its twin model (black line), and of the difference between the IGRF 2015.0 candidate model of Vigneron et al. (2015) and its twin (cyan line). All spectra are computed at Earth’s surface
