$^{*}$   Metallicity is estimated by using
equations in Carreta \& Gratton (\cite{Carreta1997}) with [Fe/H] in Zinn (\cite{Zinn1985}), and 
distance modulus is estimated from the matching of $V_{\rm ZAHB}$ and the theoretical
HB synthetic model as per Ferraro et~al. (\cite{Ferraro1999}). 
Metallicity and distance moduli of the other clusters are adopted from Ferraro et~al. (\cite{Ferraro1999}).
