Relative PSF convolution differences for the radial profiles of the disk intensity and the polarized flux for the inner disk ring model of HD 169142. Illustrated are the findings for the I′ band model and the effect of the convolution with the mean I′ PSF of the four best cycles. The remaining disk intensity I_d is shown in purple and the disk polarized intensity Q_ϕ in yellow. The correction is given by the yellow ∫Q_ϕ divided by the purple intensity ∫I_d.
