CRISM ROIs for Eberswalde Clay Origin Analysis

This dataset is a collection of regions of interest (ROIs) used in the study of the origin of clay minerals that were previously identified in Eberswalde crater, Mars. The ROIs are sorted according to the CRISM observation that they were used to analyze. Accompanying each set of ROIs is a \"bland\" ROI that was used to reduce the effects of dust on the extracted spectrum. They are either saved as .roi files or as .xml files, both of which can be opened in the GIS software ENVI. Each file has a four character alphanumeric code at the start of the name which corresponds to the CRISM observation the ROI was used to extract spectra from. This dataset includes only the ROIs that were used to analyze the clays, and not the silica.
