Chemical abundance ratios of our target stars, together with nearby APOGEE stars (d < 15′). The symbols are the same as in Fig. 1, and open symbols show abundance ratios after NLTE correction. The vertical and horizontal bars for each marker indicate the measurement error for each element, which is taken as σ/ from Tables 5 and 6. The gray cross in the upper right corner of each panel indicates the typical measurement error of the APOGEE samples.
