Values of moment tensor elements (M) are given in (r, Θ, Φ) coordinates, in which r is the radial distance of the source from the center of the Earth, Θ is colatitude, and Φ is longitude of the point source.

* The double-couple percentage (DC) is computed as 100×(1-2×e_mine_max), in which e_min and e_max are the smallest and largest absolute values of the deviatoric tensor eigenvalues.
