Notes. The quantities are listed for the standard approach in Cols. 4–6, for the case when the most massive object, UCD3, is excluded in Cols. 7–9, and for an assumed distribution of stripped nuclei in Cols. 10–12. For reference, the length of one SC formation epoch, δt, is listed in Col. 3 as determined in Schulz et al. (2015).
