Dawn Ceres Gravity Models
Status: Archived as of Oct. 5, 2018
This data set contains archival results from gravity investigations
conducted during the Dawn mission while the spacecraft was in orbit
around the asteroid Ceres. Radio measurements were made using the
Dawn spacecraft and Earth-based stations of the NASA Deep Space
Network (DSN). The data set includes a spherical harmonic model
of Ceres's gravity field generated by the Jet Propulsion Laboratory,
radial gravity acceleration map, and Bouguer map; these results were
derived from raw radio tracking data.

Superseded Versions: Show
The superseded version 1 of the data set differed slightly from the coordinate system
used in other Dawn Ceres map products delivered to PDS.
A version 2 of the Ceres L-2 gravity data products
was produced to align the coordinate system with the one utilized
by other Dawn Ceres map products. See the volume aareadme for details
of the coordinate system. Subsequently, version 3 was produced
which is fully consistent with the final SPC shape model of Ceres.
