Comparison between the three B-C-D distributions (see Sect. 4 and Fig. 4) for a vertical plane along l = 212°. The X-axis is within the Galactic plane, the Y-axis is toward the North Galactic pole direction. The color scale is the same as in Fig. 3. Iso-contours are superimposed for ρ₀ = = 0.0002, 0.00035, 0.00076, 0.001, and 0.002 mag pc^-1. The green crosses in top panel are the positions of the targets from the LVV catalog in a slice of 10 degrees around the considered vertical plane, violet crosses in middle panel are the targets from the APOGEE catalog, and the black circles in bottom panel are the molecular clouds positions and associated uncertainties based on the catalog of Schlafly et al. (2014).
