Misfit map plotted on the eigenvalue lune (Fig. 2c). The green circle depicts the best-fitting source type coordinates: lune longitude |$\gamma =5^\circ$|⁠, lune latitude |$\delta =-36^\circ$|⁠. The map shows only the best misfit value for each location on the lune, aggregated from the lowest misfit values across all orientations and magnitudes for a fixed source type, similar to the approach used for double-couple misfit maps. The depth is fixed at 33 km. The misfit map on the lune shows the best-fitting moment tensor for each source type. The double-couple and deviatoric tensor solutions from Fig. 2 are included in the full moment tensor grid and are highlighted using the same colour code as in Fig. 2.
