q (upper panel) and u (lower panel) versus distance plots using the stars distributed in a circular radius of 10° about L1570. Straight line fits were performed to estimate the foreground Stokes parameters at the cloud possible minimum distance of 324 pc. 21 stars with available polarization measurements (Heiles 2000) and distance information (van Leeuwen 2007) were only used. Care was taken to not to include stars that show emission lines or are in binary systems as given in SIMBAD.
