These mosaics were created by Philip Stooke with the assistance of Chris Jongkind and Megan Arntz. The Mariner 9 mosaic was produced with the assistance of John Pfau. Control is based on a shape model and mosaic by Peter Thomas and colleagues at Cornell University, to whom the author is very grateful for permission to use them.

Note on the Prismographic Projection (P. Stooke, unpublished, 1999): The spacing between meridians is equal to their spacing (at the equator) on the triaxial ellipsoid used as a shape model (7.8 by 6.0 by 5.1 km semiaxes). The spacing between parallels is equal to their spacing along each meridian on the triaxial ellipsoid. Different variants, approximating equivalence, equidistance and conformality, would be possible if appropriate scale factors are introduced in the y coordinate equations. In the case illustrated here the y coordinates are divided by the cosine of latitude, which increases spacing towards the poles to give a compromise between equidistance and conformality. The name 'Prismographic' indicates that the surface is projected onto a prism with the same cross-section as the body's equator. Cylindrical projections are a subset of prismographic projections.
