Caption: Figure 11.
Polarization angle (left panel) and fraction (right panel) as a function of wavelength for the six nondetections. The star shapes indicate the mean values reported in Table 4. The dashed–dotted lines in the right panel indicate the theoretical maximum polarization percentage if polarization is purely ISM caused, as per Equation (8). HD 56895 and HD 148352 have reported extinctions of 0, and thus would have zero ISM polarization contribution.
