Figure 2 in the original manuscript displays the polarization efficiency for the optical, near infrared and sub-millimeter (submm) polarimetric data as P/AV, where P is the polarization degree and AV is the visual extinction traced by the data. However, the polarization efficiency for the submm data should be simply P. By dividing P by AV, we obtain a steeper and wrong slope for the decrease in polarization efficiency. The suitable form for Fig. 2 of the original document is exhibited in Fig. 1 of the present corrigendum. The submm polarization efficiency decreases as ~−1.0 with respect to AV, instead of the originally published ~−2.0.

Although the decrease in polarization efficiency at the submm regime is shallower than originally proposed, our modelling of the polarization degree with respect to the relative intensity, I/Imax, still predicts the detection of a polarization hole (Sect. 3 of the published manuscript). Therefore, the main conclusions are unchanged.
