This mosaic covers this geographical region on Mars: 

northwest corner: 1 Lat, 79 Lon; southeast corner: -15 Lat, 

60 Lon.  It was produced using the following MOC medium

These images were processed from a raw format using 

Integrated Software for Images and Spectrometers (ISIS) to 

perform radiometric corrections and projection.  All the 

images were projected in sinusoidal using a center longitude 

of 70 degrees. There are two versions of the mosaic, one 

unfiltered (vallesmos.tif), and one produced with all images 

processed through a box filter with an averaged pixel tone of 

7.699 (vallesmosflt.tif).  Both mosaics are ArcView-ArcInfo 

ready in TIF format with associated world files (*.tfw).
