Description

Provided are (i) three types of spherical harmonic models of the gravitational field of Bennu, (ii) reference gravitational data and (iii) a spherical harmonic model of Bennu's shape.  The gravitational field models and the reference data were obtained by gravity forward modelling using a degree-15 spherical harmonic expansion of Bennu's shape and a constant mass density.

The datasets have been published in Bucha, B., Sanso, F., 2021.  Gravitational field modelling near irregularly shaped bodies using spherical harmonics: a case study for the asteroid (101955) Bennu.  Journal of Geodesy, 95, 56, https://link.springer.com/article/10.1007/s00190-021-01493-w
