\caption{\label{tab:expl}{Required} dissolution timescale ranges for globular clusters of three metallicities in four studied galaxies, as derived from the cluster samples. Due to possible incompleteness {at low masses and high $M/L$~(see Fig.~\ref{fig:expl})}, all upper limits represent minimum values and lower limits often represent maxima. Limits that do not suffer from incompleteness are shown in boldface.
