Two different definitions of abundance corrections for the example of a strong Li line on the non-linear part of the CoG. The correction is indicated by the black horizontal arrow starting on the 3D NLTE CoG (black) at A(Li) = 2.8 and ending at a higher abundance given by the intersection with the 1D LTE CoG (blue). Conversely, the correction Δ3DNLTE-1DLTE is given by the blue horizontal arrow starting on the 1D LTE CoG (blue) at the same abundance A(Li) = 2.8 and extending to the 3D NLTE CoG (black).
