Fig. 11.
Left panel: age–metallicity relation from Leaman et al. (2013) for GCs formed in situ in the MW disc (blue points) and GCs likely formed in smaller stellar systems and later accreted in the MW (red points). The size of the symbols are proportional to the IQR2 values. Right panel: cumulative distributions of GCs with different origin. The P value from two-sample K–S tests is indicated.
