Mass and Shape Determination of (101955) Bennu Using Differenced Data from Multiple OSIRIS-REx Mission Phases

This material is based on work supported by NASA under contract NNM10AA11C issued through the New Frontiers Program. S.G. acknowledges support from NASA under the CRESST II cooperative agreement with award No. 80GSFC17M0002. We are grateful to the entire OSIRIS-REx team for making the encounter with Bennu possible. Data are delivered to the Planetary Data System (PDS) according to the OSIRIS-REx Data Management Plan available in the OSIRISREx PDS archive. Raw through to calibrated data sets are available via the PDS at (https://sbn.psi.edu/pds/resource/ orex/), where there are directories for OLA (Daly et al. 2019), TAGCAMS (Bos et al. 2019), and Radio Science data. The OLA GDTM of Daly et al. (2020) can be found in the Small Body Mapping Tool available at https://sbmt.jhuapl.edu/ Object-Template.php?obj=77. Data images were generated with the freely available software GMT (Wessel et al. 2013). We thank two anonymous reviewers for their comments that improved the paper. We thank C. Wolner for editorial help.
