Dawn Ceres Gravity Models
Status: Archived, release date May 1, 2024
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.
Version 4 updates the data set with the addition of Ceres gravity models
from the extended mission.

Superseded Versions: Show
The superseded version 1 of the data set differed slightly from the coordinate system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. Version 4
adds models from the extended mission.
