CYLINDRICAL PROJECTION PHOTOMOSAIC OF DEIMOS Deimos2.gif is a photomosaic of Deimos, the outer satellite of Mars. The original mosaic, at much higher resolution than shown here, was prepared by Peter Thomas and colleagues at Cornell University. It was published in a cylindrical map projection in: Thomas, P.C., 1993. "Gravity, Tides, and Topography on Small Satellites and Asteroids: Application to Surface Features of the Martian Satellites", ICARUS, V. 105, pp. 326-344, 1993. Positions in the mosaic are controlled by a new shape model, discussed in that paper. A print of the cylindrical projection and the digital shape data were kindly provided by P. Thomas. I have used Viking and Mariner 9 images to fill a large gap in the published mosaic. This required small changes to the shape model, and the positional accuracy of the mosaic in this region (longitudes 300 to 350 degrees) is not as great as in the rest of the mosaic. This version of the file, with labels intact, is in the public domain. Philip Stooke, Department of Geography, University of Western Ontario, London, Ontario, Canada N6A 5C2 stooke@sscl.uwo.ca
