\caption{Model results for a planet at opposition 
(phase angle $\alpha=0^\circ$) with a semi-infinite 
Rayleigh-scattering atmosphere. The
columns give the single-scattering albedo $\omega$, 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
$Q_{\rm r}(r)/I(r)|_{\rm max}$.}
