Table 1.
Time events when tail I thickness becomes zero (tx0; first column), and when tail I velocity dispersion in directions x and y becomes zero (tσ, x and tσ, y, respectively; third and fourth column).

Notes. The tilt of the tidal tail x/y at the instant of zero tail thickness is written in the second column. The table is calculated for frequencies ω and κ corresponding to the potential of Eq. (27) at Galactocenric radius R0 = 8.5 kpc (i.e. ω = 8.38 × 10−16 s−1, κ = 1.185 × 10−15 s−1, ν = 2.92 × 10−15 s−1), and it lists all the events occurring in the first Gyr after the formation of the cluster.
