In this work we used a number of vibrational-rotational lines (X-2Π) from the first-overtone sequence (Δv = 2) located in
the spectral range between 1514−1548 and 1595−1632 nm. The atomic parameters of the IR OH lines and their equivalent widths measured in the target EMP giants and also the derived oxygen abundances are provided in Table A.1.
OH spectral lines used in the abundance analysis.
Abundance corrections for HD 122563.
Excerpts from CRIRES spectra centred on IR OH lines in HD 122563 (black dots). Gaussian best-fits to the observed IR OH line profiles are shown as red lines. Blue solid lines show the synthetic telluric spectrum computed with the TAPAS online service (Bertaux et al. 2014) which is shifted downwards by 0.01 for better readability. Rest frame wavelengths (λ0) and measured equivalent width values (EW) of the IR OH lines are provided at the bottom of each panel.
