Table 1: Parameters for the imaging polarimetry of Uranus and Neptune for November 30, 2003. The planet parameters were taken from the "The Astronomical Almanac 2003''. The South pole coordinates are given as distance from the disk center and position angle (see Fig. 1). For the filters the central wavelength $\lambda _{\rm c}$ and the band width $\Delta \lambda$ (FWHM) are given.
Table 2: Normalized, disk-integrated polarization parameters $\langle Q/I\rangle$ and $\langle U/I \rangle$ in the celestial coordinate system and the radial polarization parameters $\langle Q_{\rm r}/I\rangle$ and $\langle U_{\rm r}/I \rangle$ for a centro-symmetric (radial) coordinate system centered on the planetary disk. The next column gives the radial polarization $\langle Q_{\rm r}/I\rangle^{\rm corr}$ corrected for the seeing-limited resolution according to Sect. 8. The chosen seeing-correction factors are 1.22 for Uranus and 1.54 for Neptune. The last column gives the effective geometric albedo $A_{\rm g}$ for Uranus and Neptune in the corresponding filter pass band.
Table 3: 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 $Q_{\rm r}(r)/I(r)\vert _{\rm max}$ .
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 $Q_{\rm r}(r)/I(r)\vert _{\rm max}$ .
Table 5: Polarization at quadrature $\langle Q/I \rangle_{90^\circ}$ (phase angle $\alpha =90^\circ$ ) for model planets with semi-infinite Rayleigh scattering atmosperes (single scattering albedo $\omega$ ) and with finite Rayleigh scattering layer (optical thickness $b_\tau$ ) and ground albedo $A_{\rm ground}$ . Results are based on Monte Carlo simulations.
