Notes. “No FS” refers to 3D non-LTE calculations using the model atom wherein all fine structure is collapsed; “No FS / C+H exc.” refers to 3D non-LTE calculations using the same model atom, but also excluding neutral hydrogen impact excitation of C I. The uncertainties in the last column fold in uncertainties in the equivalent widths and oscillator strengths. The final row gives the weighted means, and standard error in the weighted mean, as discussed in Sect. 3.3.
