Age–[X/Fe] relations for 15 elements based on the analysis using VALD after the calibration. [X/Fe] obtained for neutral species and Sr II are shown with measurement uncertainties; red and blue solid lines mark our fits and those by M. Bedell et al. (2018), respectively. White circles indicate stars not used in the fitting (see the text).
