Table 2: 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 $0.1~M_\odot$
