Notes. (1–2) galaxy ID and spectroscopic redshift; (3–4) J2000 projected space coordinates of the overdensity (ov) peak as found by the wavelet transform; (5) projected separation between the coordinates in Cols. (3–4) and those of the SMG; (6) overdensity redshift and (7) significance as found by the PPM; (8) number of sources selected by the PPM to detect the overdensity, while between parentheses there is the corresponding average number of sources in the survey within the overdensity area and the redshift bin of 
centered around zov; (9–10) maximum radius within which the overdensity is detected as found by the PPM and by the wavelet transform; (11) adopted photometric redshift catalog. ( * ) Sources where the estimated redshift of the overdensity is marginally consistent, that is, |zspec − zov|≳0.3, with that of the SMG. ( + ) Sources where an overdensity is detected when choosing a lower parameter 
than that used for the others (see Sect. 3).
