Table 2: Abundances and isotopic ratios implied by the weak ( $\Delta v = 1$), LE ( $\Delta v = 1$) and $\Delta v = 2$ 12C16O line lists as indicator of 12C abundance. Note the large differences between 1D and 3D isotopic ratios. Note also that the HM and MARCS 1D models indicate higher abundances than the 1DAV, which in turn produces a higher abundance than the 3D model.
