Comment on “General Orthogonal Regression Relations between Body-Wave and Moment Magnitudes” by Ranjit Das, H. R. Wason, and M. L. Sharma

Das et al. (2013) describe a modification of the general orthogonal regression (GOR) method (Fuller, 1987) applied to the magnitude conversion problem that the same authors have already published at least twice in other journals (Das et al., 2012; Wason et al., 2012). Unfortunately, as more ex- haustively discussed in our comment to Wason et al. (2012), published by the Geophysical Journal International (Gasperini and Lolli, 2014), some assumptions made by the authors are wrong and therefore their method has to be rejected....
