Comparison of the age and mass derived for clusters common with San Roman et al. (2009) (panels a), b), e), f)), and for clusters common with Sarajedini & Mancone (2007) (panels c), d), g), h)). First row: comparison of the parameters of these studies vs. this work; second row: difference of the parameters derived in their studies and this work vs. the parameters derived in this work. The color-coding of clusters is the same as defined in Fig. 3.
