Correlation between the column densities of c-C₃ H₂, CH₃ OH, and A_v,eff for models #1-#8 for standard and higher metallicities. With $A_{v, e f f}^{a m b}$ $Mathematical equation: $A_\mathrm{v,eff}^\mathrm{amb}$$ =1 mag, CH₃OH shows a stronger correlation, especially at lower t_init. For $A_{v, e f f}^{a m b}$ $Mathematical equation: $A_\mathrm{v,eff}^\mathrm{amb}$$ =2 mag, the correlation is lower for CH₃OH and stronger for c-C₃H₂
