Notes. (1) Redshift of the highest density peak, (2)(3) position of the highest density peak in RA and Dec, (4) total number of structure members, (5) number of spectroscopic redshift among the members of the structures, (6) mean rest-frame U − V colors of the members obtained from the rest-frame absolute magnitudes at 3700 Å and 5500 Å, outputs of the SED fits, (7) mean rest-frame V magnitudes of the members calculated at 5500 Å, also output of the SED fits, (8) number of field galaxies in a volume comparable to the one of the corresponding overdensity, (9) structure mass estimated with Eq. (1) and assuming a bias factor b = 2 (left value) and b = 4 (right value). For the overdensities composed of a large number of multiple peaks and for the overdensities with zero spectroscopic redshifts, we do not report the number of field galaxies or the mass estimates, since the presence of spectroscopic redshifts makes the identified structures more reliable.

(a)

The structure could be composed of more than one substructure.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
