Impact of initial dust temperature (black (15 K), red (20 K), and blue (25 K) lines) and final H density (dashed lines (10⁷ cm⁻³), and dotted lines (10⁶ cm⁻³)) on simulated abundances of selected species. For all plots, black, red, and blue dashed lines are for models N7-Tg200-Td15, N7-Tg200-Td20, and N7-T2400-Td25, respectively, and black, red, and blue dotted lines are for models N6-Tg200-Td15, N6-Tg200-Td20, and N6-Tg200-Td25, respectively. Pink horizontal bar represents the observed value in G10 (see Table 3 for details of each model).
