Notes. Measurements of C, N, and O are predominantly based on molecular lines of CO, CN, and OH, respectively. For the values of excitation potential and log(gf), we directly refer to the cited lists because several lines may contribute to the flux at the given wavelength. The values corresponding to the five C I lines as well as the other atomic lines were taken from the APOGEE DR17 line list (Smith et al. 2021; Shetrone et al. 2015). Wavelengths in parentheses were removed from the line list of the automated abundance calculation of the background sample as they have been identified to provide problematic results during the visual examination of the sample fits.
