The A_V vs. d plot for all the stars classified as dwarfs towards L1122. The dashed vertical lines are drawn at 220 pc, 301 pc, and 408 pc. The dash-dotted curve represents the increase in extinction towards the Galactic latitude b =  + 14.8° as a function of distance based on the expressions given by BS80. The error bars are shown for only a few stars to be able to distinguish more clearly between the points.
