Fig. 6

Cumulative number of SC formation epochs (SCFEs) as a function of the SFR for the standard approach in blue, for the GC/UCD sample after excluding UCD3 in green, and for taking into account the stripped nuclei sample in red. The thickness of the lines depends on the value of the parameter t4 (thick lines for t4 = 3 Gyr, medium thick lines for t4 = 6 Gyr, thin lines for t4 = 15 Gyr).
