... We also identified two other spectrally unique terrains, corresponding to the northern polar ice cap, and to the southern winter polar hood. Comparisons with mineral spectra indicate the possibility of different H 2O- or OH-bearing (i.e., hydroxides and/or hydrates) minerals existing both in northern Acidalia and in the nearby intermediate albedo terrain. Hydrated minerals do not appear to be spectrally important components of the southern hemisphere dark terrains imaged by HST in 1997. ...

Meta Index / Home Page / Description The task possesses a diagnostic mode (see parameter diagnosticmode ) which facilitates a more detailed analysis of the individual HK parameter validity intervals. In this mode, in addition to the global GTI, each individual HK parameter selection expression is used to construct a corresponding GTI table which contributes to the global one. All GTI tables will be generated in a single data set named via the gtiset task parameter. ...
