Metallicities of the system corrected for dust using the refractory index B_X, with B_X values for all elements taken from Table 3 of De Cia et al. (2016) and Table 1 of Konstantopoulou et al. (2024). The blue curve represents a linear fit to Fe and Zn, with the slope δ_Z indicating dust depletion, and the intercept M_tot representing the corrected total metallicity of the system. Notably, Al and S lie above the curve, which can be attributed to α-enrichment.
