Polarization vectors of 34 bright Tycho stars plotted in the Planck 857 GHz image of LOSFR in the V band (upper panel), R band (middle panel), and I band (lower panel). The length of the vectors corresponds to the degree of the polarization values, while the orientation represents the polarization angle measured from north to east. A vector with a polarization of 2% is shown for reference. The dashed white line shows the position of the Galactic plane. The white star shows the position of λ-Ori.
