Caption: Fig. 9.
Metallicity dependence of (﹩\mathrm{NUV}\,-V﹩) colors for Milky Way GCs, galaxies, and M87 GCs in field 4. The symbols are the same as in Fig. 8. The Mg2 values for M87 GCs are estimated from their ﹩( V-I) _{0}﹩ colors. Only clusters with ﹩\sigma _{V-I}< 0.15﹩ are plotted for clarity.
