a Diagonal entries of resolution matrices for Model A, separated by satellite dataset and plotted versus coefficient number from 1 to 21,605. Inset zoom view shows the resolution of the coefficient range approximately corresponding to the gap period between CHAMP and Swarm. The lower panels show the diagonal entries of the resolution matrices for the time-varying internal field portion versus spherical harmonic degree and time for b CHAMP (left) and Swarm (right), c Cryosat and DMSP, d ground observatories, and e all data sources
