Comparison of the model abundances to observational results for different initial visual extinctions, A_V,init = 2 mag (left panels) and 3 mag (rights panels), at varying warm-up timescales: fast (top panels), medium (middle panels), and slow (bottom panels). Bars indicate the number of orders of magnitude by which each modeled abundance ratio exceeds (positive bars) or falls below (negative bars) the corresponding observed ratio. The shaded region denotes agreement within one order of magnitude. Unfilled bars with an arrow represent cases where the comparison is based on an observational upper limit. The color coding is the same as in Fig. 11.
