Age-metallicity relation for age gap clusters. The blue pentagon and red hexagon indicate the results for the characterization of SL 2 using different grids of stellar evolution models. The black-filled points refer to other age gap clusters (see Table A.2 for references). Hollow points refer to different samples of the Magellanic System: the green circles refer to different field populations in the LMC analyzed by Piatti et al. (2012), the olive triangles to LMC star clusters analyzed by Narloch et al. (2022), the purple squares refer to a heterogeneous compilation of SMC star clusters gathered by Bica et al. (2022, and references therein), plus the results from Saroon et al. (2023), and the orange diamonds indicate the results for Magellanic Bridge star clusters characterized by Oliveira et al. (2023). Black-dashed lines show the edges of the age gap: at 4 and 10 Gyr.
