Top: distribution of the parameter K0. The red line represents the kernel density plot with a smoothing width of 0.1. The black and blue line represens the best fit obtained using one and two lognormal distributions, respectively. The shaded grey and blue regions enclose the 68.3 % probability region around the best fit due to parameter uncertainties. Middle and bottom: distribution of the parameters K100 and α, respectively. The blue line with shaded area represents the best fit with a single lognormal distribution and the 1σ probability regions around it. The median value of the fit is shown directly on the graph.
