Same as Fig. 3, but in RA–Dec–z coordinates. Moreover, we overplot the location of the overdensity peaks/proto-clusters/proto-groups detected in other works in the literature (blue and green cubes, and blue and cyan crosses). Different colours and shapes are used for the symbols for clarity purposes only. Labels correspond to the IDs in Table 4. The dimensions of the symbols are arbitrary and do not refer to the extension of the overdensity peaks found in the literature.
