Table 1: Aperture photometry ( $r=1\hbox {$^{\prime \prime }$ }$ ) of the clusters in UM 462 and corrections for the contribution of the emission lines. The clusters are indicated with the nomenclature given in Fig. 1. G indicates the photometry of the whole galaxy obtained with a radius of 20 $^{\prime \prime }$ .
Table 2: Emission lines detected in the clusters. For the sources indicated by ( $\ast$ ) the $\rm H\alpha$ fluxes have been measured from the narrow band image. The fluxes are given in $10^{-15}~{\rm erg/s/cm^2}$ .
Table 3: Properties of the Clusters, the age is derived from the EW of $\rm H\alpha$ , A_V from the Balmer decrement.
