Age vs. [Fe/H] for GCs in the Local Group and NGC 2403. The orange hexagon refers to this work, turquoise circles represent GCs in the MW from Forbes & Bridges (2010), magenta circles represent NGC 2403 GCs from Forbes et al. (2022), the teal circle refers to WLM GCs from Hodge et al. (1999), the yellow circle shows Pal1 from Sakari et al. (2011), and blue and red squares show GCs with reliable parameters (those with confidence code 1) in the SMC and LMC, respectively (Horta et al. 2021).
