Projections of the target stars onto the face-on map of the Galaxy (image from Churchwell et al. 2009). Units are parsecs, counted from the Sun, with d_Sun ≃ 8 kpc. The color-coding corresponds to the equivalent of the 6283 Å DIB, either directly measured, or, when not measured, estimated from the other DIB measurements using the average EW(6283)/EW(8620) or EW(6283)/EW(6614) ratios computed from the whole dataset. The black asterisk and small arrow mark bulge field 5 (Baade’s window direction) for which the X coordinate has been multiplied by 4 to avoid confusion with the other directions. The Galactic latitude of each field is indicated at the extremity of the sightline.
