Notes. The SPA slopes correspond to the sample of 18 OCs presented in Zhang et al. (2022). For OCCASO, the slopes correspond to 36 OCs in the recent work of Carbajo-Hijarrubia et al. (2024). Values for [X/Fe] ratios and ages are taken from the original papers. For OCCAM, the slopes are based on 84 high-quality OCs from APOGEE DR17 Myers et al. (2022), except for Na (64), Al and Mn (82), and Co (61).
