\caption{Cluster data. Photometry is corrected for foreground
  reddening only. $\Delta A_B$~is the additional amount of reddening
  required to best match the SSP~model colours. The ranges of turn-off
  and total cluster masses reflect the differences between spectroscopic
  and photometric age estimates. The masses are for a~Salpeter-like
  IMF with a~lower mass limit of $0.1~M_\odot$}\label{tab:phot}
