Data Set Overview

This data set collects the maps of small solar system bodies prepared by Phil Stooke of the University of Western Ontario. A total of 226 map sheets, including 18 new ones added in 2011 and 5 new ones in 2012, are included, some based on photomosaics from spacecraft images and some based on shaded relief maps prepared from spacecraft images. The targets included are Asteroids - 243 Ida, 253 Mathilde, 433 Eros, 951 Gaspra, and 25143 Itokawa. Satellites - M1 Phobos, M2 Deimos, J5 Amalthea, S7 Hyperion, and S11 Epimetheus. Comets - 81P/Wild 2 For these maps, the prime meridian is defined according to the existing literature for each body. For all synchronously rotating satellites (Phobos, Deimos, Amalthea, etc.) the prime meridian faces the primary planet. For Gaspra, Ida, and any other objects not in synchronous rotation, the prime meridian is that used in the basic descriptive papers by Peter Thomas and colleagues for each body, and given in the IAU Working Group on Rotational Elements and Cartographic Coordinates triennial reports. Longitudes in every case increase in the direction opposite to rotation. Data ==== The map sheets are provided as jpeg files in the document directory of the data set, supported by an html browse page (aamapdesc.html) and a document describing the map projections used (projections.asc). In the data directory is an index listing the parameters describing each map (, as well as FITS versions of all the maps which were prepared by SBN from the original map files, as requested at the 2012 peer review for the convenience of data users. The FITS versions have the same filenames as the corresponding jpeg map sheets in the document directory, but with the extension changed to .fit. The information in the browse page, the projection description, and the index were provided to PDS by Phil Stooke.

Archiving History

This data set supersedes the PDS data set EAR-A-3-RDR-STOOKEMAPS-V1.0 which was reviewed and archived in 2003. The 2011 version of the data set (MULTI-SA-MULTI-6-STOOKEMAPS-V1.0) has the same content as the earlier data set with the addition of 18 new map sheets, and including new target bodies 25143 Itokawa and Comet 81P/Wild 2, and new maps for 433 Eros, Phobos, and Deimos. The 2012 version (V2.0) adds five map sheets, one on Itokawa and four on Comet 81P/Wild 2.
