Notes. Columns (1) and (2) are the ID and the redshift of the peak, as in Table 2. Column (3) is the average matter overdensity derived from the average galaxy overdensity of Col. (7) of Table 2. Columns (4) and (5) are the redshifts when the overdensity reaches the overdensity of turn-around and collapse, respectively. Columns (6) and (7) are the corresponding time intervals Δt since the redshift of observation zobs (Col. 2) to the redshifts of turn-around and collapse. When zta < zobs the turn-around has already been reached before the redshift of observation, and in these cases the corresponding Δt have not been computed. See Sect. 5.1 for more details.
