Wavelength dependence of the measured relative intensities I_disk∕I_total and polarized intensities Q_ϕ,disk∕I_total for the scattered light from the disk in HD 142527. The colored symbols are from Table 3, the values marked with (F06) from Fukagawa et al. (2006) and (A14) from Avenhaus et al. (2014). The values (H09) from Honda et al. (2009) are given in an inset with an arbitrary scale factor to offset them from the other data because these are relative measurements for an area at the southwest rim of the disk.
