Polarized intensity of HD 142527 in the VBB (a) and H-band (b) and the corresponding surface brightness Ĩ_disk(φ), maximum polarized surface brightness and degree of polarization p_disk(φ) in (c) and (d), respectively. The azimuthal surface brightness profiles in (c) and (d) show theaverage surface brightness for the four brightest values (indicated by the green dots in (a) and (b)) in each radial profile (see Appendix A). The values are not corrected for signal loss due to PSF smearing. The plots for the azimuthal degree of polarization also show the degree of polarization at the positions where the highest surface brightness was measured (green dots), and additionally show the intensity-weighted average polarization for the complete radial profiles (dashed line).
