The first four columns list the cluster NGC number, the predicted V-band mass-to-light ratio  $(M/L_V)_{\rm pred}$, the logarithm of the initial cluster mass  $\mbox{$M_{\rm cl,i}$ }$ and the remaining lifetime  $\mbox{$t_{\rm dis}^{\rm total}$ }-t$. In the fifth and sixth column, respectively the ratios of observed to canonical mass-to-light ratio  $\mathcal{Q}_{\rm obs}$ and predicted to canonical mass-to-light ratio  $\mathcal{Q}_{\rm pred}$ are listed. The seventh column gives the level of agreement between the observed mass-to-light ratio  $(M/L_V)_{\rm obs}$ and predicted mass-to-light ratio  $(M/L_V)_{\rm pred}$ (see text).
