On-source column densities for select COMs using a 1 arcsec beam convolution. The red bars illustrate column densities for the 3.0 × 10⁻³ M_⊙ yr⁻¹ model, the blue bars illustrate column densities for the 1.0 × 10⁻³ M_⊙ yr⁻¹ model, and the orange bars illustrate column densities for the 1.0 × 10⁻⁴ M_⊙ yr⁻¹ model. Panel a shows column densities for the initial stage-2 simulation time, panel b shows column densities for stage-2 simulation times that correspond to a temperature of 100 K, and panel c shows column densities for the final stage-2 simulation time. It should be noted that the ranges for the vertical axis differ for all panels.
