For each magnitude mj, if Nj is the number of values of magn1
greater than mj,
the values of log(Nj) vs. mj are plotted.
According to the Gutenberg-Richter law, this plot should be linear. If there is a linear behaviour only for values greater than a given m0, then m0 is probably the magnitude threshold of the catalog.
A new plot is printed (see details).
