A_V vs. d plot for all stars obtained from the fields F1-F6 combined toward L1570. The dashed vertical line is drawn at 394 pc inferred from the procedure described in Maheswar et al. (2010, see the text for a brief description). The dash-dotted curve represents the increase in the extinction toward the Galactic latitude of b =  −0.4591° as a function of distance produced from the expressions given in Bahcall & Soneira (1980). The error bars are not shown on all stars for clarity.
