Sky distribution of galaxies in the XLSSsC N01 supercluster region. Top left panel: galaxies with a photo-z redshift in the range between 0.25 and 0.35 and used to compute the LD (black points). Top right panel: galaxies with a spectroscopic redshift, colour coded according to their environment (see Sect. 3). Grey crosses are low-density field galaxies, green dots are high-density field galaxies, dark orange diamonds are virial members, and black stars are outer members. In the top panels, black circles show the projected extension in the sky of 3 r200 for each cluster in the superstructure. The two bottom panels show the low- and high-density field samples separately, with the same symbols as the top right panel.
