\begin{eqnarray}
\label{eqn:convert_from_actual_to_observed_density}
\rho(\Gamma_{\rm obs}, P_{\rm obs}) = & \int_{b = 0}^{b_{\rm max}} & & f\ \rho(\Gamma_{\rm act}(b), P_{\rm act}(b)) &\ & \dfrac{2b\ db}{b_{\rm max}^2} & \\
= & \int_{b = 0}^{\frac{1}{2} \sqrt{\Gamma_{\rm obs}^2 - \Gamma_{\rm min}^2}} & & f\ \rho(\Gamma_{\rm act}(b), P_{\rm act}(b))& \
& \left( \Gamma_{\rm obs}^2 - \Gamma_{\rm min}^2 \right)^{-1}\
& 4b\ db &.
\end{eqnarray}
Figure \ref{fig:uniform_actual_distribution_to_observed_distribution} shows the result for a uniform distribution for underlying values, $\rho(\Gamma_{\rm act}, P_{\rm act}) = \left( P_{\rm max} - P_{\rm min} \right)^{-1}\ \left( \Gamma_{\rm max} - \Gamma_{\rm min} \right)^{-1}$ and compares it to a simulated dust devil survey (blue circles).
