Testing Correspondence between Areas with Hydrated Minerals, as Observed by CRISM/MRO, and Spots of Enhanced Subsurface Water Content, as Found by DAN along the Traverse of Curiosity

Table 1

Comparison of parameters of WEH distributions for groups of CRISM pixels. WEH is derived from the DAN passive data for the case of long-range variability of AEC (LR case).

Groups of CRISM pixels		Coverage of the traverse (%)	Number of CRISM pixels	Number of DAN measurements	Mean of the WEH distribution (wt%)	Variance of the WEH distribution	χ^2 for Pearson criteria	-level for Pearson criteria
Reference distribution		81	831	5467	2.54 ± 0.02	0.33	—	—
Phyllosilicates		5	51	293	2.57 ± 0.07	0.27	1.55	0.908
Monohydrated sulfates		4	45	307	2.41 ± 0.09	0.33	7.74	0.257
Polyhydrated sulfates	All	10	101	638	2.78 ± 0.05	0.25	24.30	0.0005
	Of “high intensity”	5	50	312	2.88 ± 0.07	0.24	21.79	0.0006
