Notes. Here, r is the Pearson correlation coefficient, p its significance, and the EW medians are given for low (< 50) and high (≥50) activity levels together with the difference (ΔEW) between the two values. 3D NLTE abundances A(O) are calculated for the two bins, with the matching difference ΔA(O).
