Thus,  \begin{eqnarray}  \label{eqn:}  \dfrac{d}{db} \bigg[ \bigg(  \rho(\Gamma_{\rm obs}, P_{\rm obs}) - \rho(\Gamma_0, P_{\rm min}) \bigg] \bigg)  = \dfrac{d}{db} \left[ \left(  \int_{b^\prime = 0}^{b} f\ \rho({\rm act}) \dfrac{2b^\prime\ db^\prime}{b_{\rm max}^2} \right] \right)  \\ \Rightarrow b^{-1}\ P_{\rm obs} \left[ \left(  \dfrac{\partial \rho({\rm obs})}{\partial P_{\rm obs}} - \left( \dfrac{\Gamma_{\rm obs}}{2 P_{\rm obs}} \right) \dfrac{\partial \rho({\rm obs})}{\partial \Gamma_{\rm obs}} \right] \right)  = b_{\rm max}^{-2}\ f(b)\ \rho({\rm act}(b))\ b \end{eqnarray}
