Eff., Effective source dimensions, computed using Mai and Beroza (2000); 1 Norm, L1 norm; 2 Norm, L2 norm; RMSE, root mean square error; SIV, Source Inversion Validation; VR, variance reduction. Bold entries refer to the true known solution, whereas all other entries refer to the inferred models by various authors.
