The data sets listed in the table below are PDS3 legacy data sets. Once these data sets have been migrated to PDS4 they will be listed in the section above.

|Data Resource Page
|Dawn GRaND Ceres Maps
|This data set contains the Dawn Ceres high level map products including Water Equivalent Hydrogen (WEH) Map, Smoothed Water Equivalent Hydrogen (WEH) Map, Thermal & Epithermal Neutron Counts Map, Iron Concentration Map, and Iron Gamma Counts Map. These maps have been generated from the GRaND L1B data taken during the Ceres Low Altitude Mapping Orbit phase of the Dawn mission.
|HST Images, Albedo Maps, and Shape of 1 Ceres
|This dataset contains 267 HST ACS/HRC images of asteroid (1) Ceres obtained in 2003/2004 at three wavelengths, 535 nm, 335 nm, and 223 nm. They have been photometrically calibrated to standard reflectance unit I/F. The dataset also includes a shape for Ceres, as well as three surface albedo maps covering the area between +/-50 deg latitude, derived from these images.
|Dawn VIR Ceres Global Maps
|This data set contains global mosaics of the Dawn VIR band centers and depths of phyllosilicate absorption bands, located at 2.7 (OH band) and 3.1 microns (NH4 band), from the Ceres encounter. The data set was acquired during the Survey and Ceres Science RC3 (CSR) phases between 2015-04-25 and 2015-06-27.
|Dawn Shape Models of Ceres LAMO
|This data set contains a Ceres regional digital terrain models and associated clear filter mosaics based on the Dawn Low Altitude Mapping orbit (LAMO) Framing Camera 2 (FC2) images and derived by using the stereo photo-grametric (SPG) method. The LAMO DTMs/mosaics covers the regions around the following features: Ahuna Mons and the Occator, Ernutet, Haulani, Ikapati, Kupalo/Juling, and Yalode craters. The DTM has a lateral spacing of 32 m/pixel (256 pixel/degree) and a vertical accuracy of about 1.5 m.
|Dawn Shape Models of Ceres HAMO
|This data set contains the Ceres digital terrain model based on the Dawn High Altitude Mapping orbit (HAMO) Framing Camera 2 (FC2) images and derived by using the stereo photo-grametric (SPG) method. The HAMO DTM covers approximately 98% of the Ceres surface (few permanently shadowed areas near the poles required interpolation). The a DTM has a lateral spacing of ~136.7 m/pixel (60 pixel/degree) and a vertical accuracy of about 10 m.
|Dawn Ceres Gravity Models
|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 Bouguet map; these results were derived from raw radio tracking data.
|Dawn Framing Camera Ceres Image Mosaics
|This accumulating data set includes Ceres global mosaics and quadrangles derived from images acquired by the Framing Camera 2 (FC2) on the NASA Dawn spacecraft. Global mosaics are provided in cylindrical and polar stereographic projections. The quadrangle mosaics use Mercator (equatorial), Lambert conformal (mid-latitude) and stereographic projections. Clear and color mosaics are provided for high altitude mapping orbit (HAMO) and clear filter mosaics only in the low altitude mapping orbit (LAMO) science phases.
