Polarization position angles (bars) of a magnetic filament that is roughly parallel to the interstellar magnetic field shaping the heliosphere are plotted for stars within 20 (red) and 40 (blue) parsecs. Stars with p∕e_p less than 1.95 are plotted as dots. The green dashed line indicates the direction of the ISMF shaping the heliosphere as determined from the center of the IBEX ribbon of ENAs (see Sect. 3.2). Data are plotted in Galactic coordinates (l, b).
