Crater Calibration

        This mosaic was acquired by the Mars Exploration Rover Opportunity on Sol 1377 (December 8, 2007).  The extensive martian dust storm that took place during 2007 left dust on the optics of the Pancam cameras. This image, taken after the storm had subsided, was intended to help calibrate how much image overlap should be used in upcoming mosaics to minimize obscuration by dust. Although increased overlap improves the mosaics, the effects of dust are still visible in the left seam and on the right side of the mosaic. Pancam's 753nm, 535nm, and 432nm filters were used in this mosaic.  Two versions are available below at full resolution: an approximate true color rendering, and a false color stretch to enhance the subtle color differences in the scene.
