^* Metallicity is estimated by using equations in Carreta & Gratton (1997) with [Fe/H] in Zinn (1985), and distance modulus is estimated from the matching of $V_{\rm ZAHB}$ and the theoretical HB synthetic model as per Ferraro et al. (1999). Metallicity and distance moduli of the other clusters are adopted from Ferraro et al. (1999).
