Notes. The columns give the filter, the central wavelength λ_c, the effective wavelength λ_eff, the effective albedo A_g,eff for the photons registered in the broad-band filters, and the Toon et al. (1992) radius R_T for λ_eff. ⟨ Q/I ⟩ _m, ⟨ U/I ⟩ _m, ⟨ Q_r/I ⟩ _m, and ⟨ U_r/I ⟩ _m are the measured disk-integrated polarization parameters. The parameter C_PSF describes the degradation of the polarization measurement due to the PSF smearing effect (Sect. 6.4), and the corrected radial polarization value is given by ⟨ Q_r/I ⟩ = ⟨ Q_r/I ⟩ _m/C_PSF. is the measured maximum radial polarization, whereas (Q_r/I)^max is the modeled value for infinite resolution. The statistical 1σ error for the disk-integrated polarization is estimated to be Δp ≤ ± 0.1% and ΔC_PSF = ± 0.01. In addition, a systematic uncertainty of (Δp)_syst. ≈ ± 0.2% is estimated.
