Left column: CMDs for the Arm 2 in the field 1 at different distances from the center of the arm. Middle column: best fit CMDs assuming solar and LMC like metallicities, a binary fraction of 0.5 with a mass ratio between 0.1–0.9, and a fixed A_B foreground extinction of 0.29. Right column: best fit CMDs assuming solar metallicity, a binary fraction of 0.5 with a mass ratio between 0.1–0.9, and a fixed A_B foreground extinction of 0.29. The fits were done using the red boxes shown in the figure.
