Extrapolation of the KLF power-law fit. The KLF slope of α = 0.18 and the upper limit imposed by the uncertainty in the fit (α = 0.25) are plotted as dashed and dash-dotted lines, respectively. The black filled circles represent the data while the hollow circles represent new points based on the extrapolated KLF slope. The approximate location of the detection limit is indicated by the vertical dotted/red line.
