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
(mapindex.tab), 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.
