Table 4: Parameters for planets at opposition (phase angle $\alpha =0^\circ $) with finite Rayleigh scattering layer (optical thickness $b_\tau $) and ground albedo $A_{\rm ground}$. The tabulated values are the geometric albedo $A_{\rm g}$, the disk-integrated radial polarization $\langle Q_{\rm r}/I\rangle$, the line-integrated radial polarization for a line through the disk center, and the maximum radial polarization $Q_{\rm r}(r)/I(r)\vert _{\rm max}$.
$b_\tau $ $A_{\rm ground}$ $A_{\rm g}$ $\langle Q_{\rm r}/I\rangle$ $\langle Q_{\rm r}/I\rangle_{\rm line}$ $Q_{\rm r}/I\vert _{\rm max}$
