Best fitting parameters of bimodal model for WEH distribution for the group of CRISM pixels with the signature of polyhydrated sulfates (cases of LR and SR are presented for estimations of WEH from the DAN passive data).

Distributions of WEH for CRISM pixels along the rover traverse		Fraction of the component of bimodal model representing polyhydrated sulfates (in parts of 1)	Parameters of the normal distribution of WEH for the component of bimodal model representing polyhydrated sulfates		χ^2 minimum value	-level
			Mean (wt%)	Variance
Polyhydrated sulfates	According to the LR case	0.37	3.00	0.24	6.75	0.150
Polyhydrated sulfates of “high intensity”		0.99	2.87	0.43	8.78	0.032
Polyhydrated sulfates	According to the SR case	0.12	3.59	0.19	17.29	0.001
Polyhydrated sulfates of “high intensity”		1.00	3.13	0.22	5.64	0.060
