Notes. Columns are: Desorption temperature (taken as the recommended peak desorption temperature in Minissale et al. 2022 under high-density conditions), abundance with respect to total H (Ballering et al. 2021), molecular weight, disk regions in which the ice is distributed and references for the optical constants. Disk regions are numbered from warm to cold in steps of one ice component.
