Table 5

Parameters used to perform the models shown in Fig. 5.

H2O ice H2O ice grain Additional slope Goodness
abundance (%) size (μm) (%μm-1) χ 2

1.3 750 2.8 2.78
0 750 4 31.2
2.6 750 0 15.0
1.3 75 2.5 9.4
1.3 7500 3.9 6.8

Notes. The first line represents the best fit (reported in Table 4) shown in red in both panels of Fig. 5. The abundance and grain size of water ice in areal mixture are fixed as: 0% and twice the abundance retrieved for the best fit, and one tenth and ten times the grain size retrieved for the best fit. The additional slope (free parameter of the model) and the resulting goodness are indicated in the table.
