Left panel: spatial density map of the clustered population extracted from Fig. 10, overplotted to the map of the complete catalog population (gray dots). Colors progress with local number density of objects from red (lowest) to blue/purple (highest) following a rainbow scale. Points encircled in black are possible giant contaminants (see Sect. 4.1). Right panel: A_V distribution of objects highlighted in the left panel, after removing the giant contaminants. Colors are scaled according to A_V as shown in the side axis. The field population is shown in gray in the background. Fuchsia triangles mark the locations with the highest density of objects from the clustered population (in blue on the left panel diagram).
