The SBMT contains images from the PolyCam and MapCam instruments from the OSIRIS-REx Camera Suite (OCAMS). OCAMS data are available at https://sbn.psi.edu/pds/resource/orex/ocams.html (Rizk, B., C. Drouet d'Aubigny, D. Golish, D.N. DellaGiustina, and D.S. Lauretta, Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx): OSIRIS-REx Camera Suite (OCAMS) Bundle, urn:nasa:pds:orex.ocams, NASA Planetary Data System, 2019.)
In addition to individual images, certain Bennu models also come with global basemaps. These include the panchromatic basemap from Bennett et al. (2020), and false-color Red-Green-Blue (RGB) composites of asteroid Bennu from DellaGiustina et al. (2020). RGB color channels are: red, x/v (0.85/0.55 μm, mid-VIS to NIR spectral slope); green, w-band strength (depth at 0.70 μm, composition), and blue, b/v (0.47/0.55 μm, near-UV spectral slope). These colors have been overlaid on a 0.55-μm (v band) normal reflectance map of Bennu. Saturated regions in these basemaps (pixel values of 255) represent areas with no data in the basemap.
The SBMT contains images from the NavCam instrument of the OSIRIS-REx Touch-and-Go Camera Suite (TAGCAMS). NavCam data are available at https://sbn.psi.edu/pds/resource/orex/tagcams.html (Bos, B., C. Jackman, and D.S. Lauretta, Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx): Touch-and-Go Camera Suite (TAGCAMS) Bundle, urn:nasa:pds:orex.tagcams, NASA Planetary Data System, 2019.)
The SBMT contains OSIRIS-REx laser altimeter (OLA) data. OLA data are available at https://sbn.psi.edu/pds/resource/orex/ola.html (Daly, M.; Barnouin, O.; Espiritu, R.; and Lauretta, D., Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx): OSIRIS-REx Laser Altimeter Bundle, urn:nasa:pds:orex.ola, NASA Planetary Data System, 2019.)
The names of files in the SBMT sometimes differ from the names of the same data product in the PDS. The SBMT and PDS file names similar information, which makes it straightforward to correlate filenames, should a user want to retrieve data directly from the PDS. Here are some examples for each instrument to clarify how the names relate.
