Notes. These candidates are ranked by the possibility of residing in overdense regions, accounting for factors such as the number of Herschel-detected neighbors, the spatial neighbors found in the deep photo-z catalogs, or the quality of their redshifts (specscopically confirmed or the reduced χ2 in the fitting for photometric redshifts), whether they are determined by the FoF algorithm and the q value in FIRC (defined as log
; smaller values indicating more radio-loud).
EN1_23891 is 18.4′ away from the protocluster candidate PCCS1 857 G085.48+43.36 in Greenslade et al. (2018), in spatial volume of 7.78 Mpc at z = 4.11. Boötes_13499 is 4.39′ away from the protocluster candidate PLCKERC545 G060.36+66.56 in Greenslade et al. (2018), in spatial volume of 2.23 Mpc at z = 2.18.
