Extinction and distance of 43 stars estimated using the method described in Sect. 4.1 (top panel). Degree of polarization (%) versus distance and position angle versus distance plots for these stars are shown in the middle and bottom panels, respectively. The broken line is drawn at a distance of 450 pc where the first abrupt rise in the value of extinction was seen. The open circles show the polarization results obtained from the Heiles (2000) catalog of stars selected from a region of 20°× 20° field containing Gal 110-13 and Gal 96-15 clouds. The distance to these stars are calculated using the new Hipparcos parallax measurements given by van Leeuwen (2007).
