Results of non-LTE EW fitting with various model atmospheres for given disk-center equivalent width W1 (as measured from the Pereira data set, see Table 2) and SH-factor (as obtained from the global EW fit with the 3D model, see Table 3).

Notes. The oxygen abundance A(O) required to reproduce W1 with the 3D, averaged 3D, HM, and LHD model, respectively, is listed in Cols. (4)–(7). For all 1D models, a microturbulence of ξmic = 1.0 km s-1 is assumed.
