Best-fit polarization curves assuming beta distribution from RDI KLIP forward modeling in Figure C.1, the peak polarization locations are marked with circles. The light gray curves denote scattering angle ranges that are not accessible for inclined thin disks with no flaring. (a) Direct conversion: the extracted profiles are different even for the same system (i.e., B₁ and B₂). (b) Conversion with Savitzky-Golay filtered Q_ϕ data: the extracted curves are less distinct, since such reductions are less prone to pixel-wise discrete noise.
