Ice compositions predicted by MAGICKAL for NIR38 for the models listed in Table 2. Left panel: Predicted water ice column densities. Wide right panel: Ice column density ratios with respect to water for the remaining species. Histograms are coloured and drawn as indicated in the upper right part of the panel. The visual extinction and dust temperatures assumed in the models are reported in the upper part of the panel. Black wide histograms report the observed Ice Age column density of water and ice column density ratios obtained by McClure et al. (2023). The 3σ error bars are also shown. -- astro-ph.GA
