Formal upper limits of the components not significantly detected in the fitting procedure.

Name Upper limit

Water ice – direct deposit 40% of Mice
Water ice – warmup 40% of Mice

Montmorillonite 47% of Mdust
Serpentine 29% of Mdust
Chlorite 8% of Mdust
Dolomite 3% of Mdust
Calcite 2% of Mdust

Notes. The upper limits are derived for inclusion of single components to the best fit. For example, either the direct deposit or the warmup ice components can be added with an abundance of 40% compared to the cooldown ice component. The dust mass Mdust includes the mass in the crystalline ice component.
