Fig. 2.

The proposed histogram function of envelope amplitudes $A$, having the form $A/{(A^2+a_{\min })}^b$. (a) Normalized functions, where $a_{\min }=1/2$ and the power law parameter $b$ is 3, 2.5, 2, and 1.5, are shown. (b) Normalized functions where the power law parameter is fixed at 2.5, however, $a_{\min }$ is varied as 1/4, 1/2, 3/4, and 1. Vertical axis: counts (arbitrary units); horizontal axis: envelope amplitude (arbitrary units).
