\label{fig:n-Gammaobs_from_uniform-n-Gammaact} Number densities \(n(\Gamma_*)\) of a population of dust devil pressure profile widths. The solid, blue line shows a uniform distribution of \(\Gamma_{\rm act}\)-values, while the dashed, green shows the corresponding distribution of \(\Gamma_{\rm obs}\)-values predicted by the analytic model (Equation \ref{eqn:n-Gammaobs_from_uniform-n-Gammaact}). The units are arbitrary. In contrast to previous similar figures, the x- and y-axes are linear, not logarithmic.
