Absorbance spectra obtained by JWST towards the background stars NIR38 (top) and J110621 (bottom) in the Chamaeleon I molecular cloud, and predictions obtained by AICE for the corresponding ice composition and temperature. Left panels: absorbance spectra (in black) obtained after the reduction of the original JWST spectra in flux (McClure et al. 2023). Right panels: direct numerical predictions given by AICE of the fractional molecular composition and temperature of the corresponding ices towards both positions (grey bars and black points), compared to estimates obtained by other authors (in pink, McClure et al. 2023; in orange, Dartois et al. 2024).
