1D NLTE vs. 1D LTE abundance corrections for the 777.4 nm component of the O I 777 nm triplet as a function of effective temperature. Literature results of Luck et al. (2013) based on 1D ATLAS9 model atmospheres are shown as black stars. Our 1D results are shown as dots taking effective temperatures and gravities from the three-day (red) and nine-day (blue) Cepheid model.
