From: A Swarm lithospheric magnetic field model to SH degree 80
Left Lowes–Mauersberger power spectra of the lithospheric field for degrees 15–80 of the DLFI model and various models at the Earth’s surface (solid lines) and their difference with the MF7 model (dashed line). The statistical power (SP) is in magenta. Center degree correlation between the models and the MF7 model. Right azimuthal power spectrum of the models. For each quadrant, the MF7 model is indicated in black, the SIFM in red, and the DLFI model in blue
