(a) and (c) Reflectance versus ${\mu }_s^{\prime }{f}^{-1}$ calculated with the Hankel transform of Eq. (6) for the $R_{\mathrm{PCBC}}(\rho ,z_0)$ (red lines) compared to $R_{\text{Cuccia}}$ [Eq. (4), blue lines] and (b) and (d) the model for $R_{\mathrm{PCBC}}(k)$ [Eq. (10), black lines] for two sets of optical properties as indicated in each subfigure. $R_{\text{Cuccia}}$ does not match the Hankel transform of Eq. (6) for the $R_{\mathrm{PCBC}}(\rho ,z_0)$, while $R_{\mathrm{PCBC}}(k)$ does match.
