Fig. 11.
Top panel: distribution of [Fe/H] of GCs against de-projected radius. The red and blue circles represent the GCs younger and older than 14 Gyr, respectively. The squares represent the mean metallicity values in different de-projected galactocentric distance for the GCs. The two dashed lines represent metallicities [Fe/H] = −0.4 and [Fe/H] = −1.5. Middle panel: age vs. de-projected radius. Bottom panel: mass vs. de-projected radius.
