Line profiles as predicted by the fiducial model with HM abundances, 10⁶ yr static phase, and $A_{v, e f f}^{a m b}$ $Mathematical equation: $A_\mathrm{v,eff}^\mathrm{amb}$$ = 2 mag. The spectra were extracted toward the continuum peak in the x-y plane. A fixed ¹⁶O/¹⁸O ratio of 560 was used for the C¹⁸O abundance profiles.
