Radial and [O/H] (upper panels) and [Si/H] (lower panels) gradients at 1 < Age/Gyr < 3 (left panels) and Age < 1 Gyr (right panels) for the model 3INF-2, including stellar migration and average OC spread (see Section 3.4). Lines show the results for the [Fe/H] gradient as predicted by the model at Ages=0.5 Gyr (cyan lines), 1.8 Gyr (green dashed lines), and 2.8 Gyr (green solid lines). Filled circles represent the restricted sample within OCs in Magrini et al. (2023).
