Notes:
General moment-tensor solutions contain double couples, compensated linear vector dipoles (CLVD's) and isotropic sources. Since double-couple solutions are considered to be standard, it is important to find the best double-couple solution that is consistent with the original solution. It is proved that for a number of reasonable measures of fit, the best double couple is the one formed by removing a CLVD source with a magnitude of the intermediate non-zero eigenvalue. It is also shown that mixtures of double couple and CLVD's may result from near-source changes in rigidity.
