| Photo-z density map center | [αJ2000,δJ2000] = [02:26:55.2, −04:20:45.6] |
| Number of spectral members | 19 (6)a |
| Median redshift |
|
| Spectral overdensity | δgal = 10.5 ± 2.8, σProto − Struct. = 13.5 |

Notes.
The first number refers to all spectroscopically confirmed members with Rproj< 3
Mpc and 3.27 <zspec< 3.35. The number in parentheses refers to tentative members with less reliable redshift measurements (see Sect. 2.1).
This number refers to the formal significance of the detection after accounting for spurious density peaks (see Sect. 3.1).
