Stellar populations of FCC 224 and comparison with DF2 and DF4. Resolved mass-weighted age (t_M) and metallicity ([M/H]) profiles for FCC 224 along the circularised effective radius of the galaxy (orange squares, shaded uncertainties) compared with DF2 (Fensch et al. 2019a) (green squares, shaded). Stars denote integrated stellar populations for FCC 224 (orange), DF2 (green) and DF4 (purple), and circles indicate stacked GC populations for FCC 224 (orange) and DF2 (green). GC stellar population information is not available in the case of DF4. The flat profiles in FCC 224 and DF2 suggest coeval star and GC formation.
