Distribution of the SMGs and associated protocluster galaxies in the RA, Dec, and redshift space when the B19, L18, and AH18 photometric redshift catalogs are used for the detection of protoclusters. Small gray and colored dots always correspond to sources from the B19 catalog, which is chosen for a better visualization as it is the largest photometric redshift catalog. Red squares show the location of the SMGs in our sample. Colored clouds show the members of the overdensities as identified with the PPM. Protocluster members are color coded in yellow, green, and blue according to their increasing redshift. Interactive 3D plots for all three photometric redshift catalogs are available online.
