Left: correlation of debiased polarization fraction in emission with that in extinction (Pearson coefficient 0.74). Right: correlation of the debiased polarized emission (in MJy sr^-1) with starlight polarization degree (Pearson coefficient 0.87). The range corresponds to one quadrant in Fig. 7. The fits are forced to go through the origin and have slopes R_{S /V} = 4.18 ± 0.04 () and R_P/p = (5.41 ± 0.04) MJy sr^-1 (), respectively.
