Unweighted posterior residual fit of the parent model to Swarm data. Left: Residuals by GMD latitude. Right: Residuals by time, with high-latitude (\(\ge |\)55|\(^\circ \)GMD latitude) data marked in grey, and mid- to low-latitude data in colour. Note the data are downsampled for simpler visualisation, but retain their 2\(\sigma \) outliers. Data numbers count vector triples as one
