Extended Data Figure 7: Slices through the mass-anomaly parameter-space search.

a–d, Coloured contours enclose regions where placing a mass anomaly ΔQ of the indicated size will cause a reorientation of the Moon to within the specified distance (see legend) of the present-day lunar spin pole. Red filled circles denote the epithermal neutron palaeopole. e, Contours enclose regions where mass anomalies ΔQ must be centred to reorient the Moon from the epithermal neutron palaeopole to the present-day spin pole, to within 1°. This figure is the same as in Fig. 3a–c, but in an equirectangular projection; symbols and lines as in Fig. 3a–c.
