Results for target stars in field 1 (CoRoT anticenter). 6614 Å DIB EW (top), 8620 Å DIB EW (middle) and extinction A₀ (bottom) vs. the estimated distance. Circles show GIRAFFE observations. Triangles show UVES observations. Colors in the top panel correspond to the number of IS components used to fit the IS line or band. All nearby targets (D ≤ 1 kpc) have only one IS component, or, for three targets, a very weak, negligible second component. Distant targets have more than one velocity component, in agreement with the crossing of at least one external arm (see the text). The outlier star 06441428-0057447 marked by a red star has stellar spectroscopic parameters that strongly disagree with stellar seismology information, which indicates that their distance and extinction are inaccurate for this target.
