Figure 2.

Flux distribution function. ½ ln(〈(ΔJ)²〉) + ln(P(J)) is plotted against ($(J-\langle J\rangle )∕\sqrt{2\langle {\left(\Delta J\right)}^2\rangle }$, based on the form indicated by eq 3. The circles indicate experimental points, and the line shows a quadratic fit to the data. The coefficient of determination, R², for the fit is also reported. This demonstrates that the distribution function is Gaussian, and we find that the coefficients are well predicted by eq 3.
