Agemetallicity relation for GCs with known rotation properties. The normalised ages are taken from Marín-Franch et al. (2009) based on the Zinn & West (1984) scale. The points are colour-coded based on the Arot/σ0 ratio. Slow rotators are marked with red and fast rotators with blue. NGC 4372 is marked with a red star. The two sequences of GCs supposedly accreted into the Milky Way halo and born in-situ are marked with black lines.
