VizieR Online Data Catalog: Phoebe Spherical Harmonics decomposition (Rambaux+, 2020)
Abstract
Phoebe has been observed by the Cassini-Huygens spacecraft in 2004. From these observations a Digital Terrain Model (DTM) was built by B. Gaskell. It is accessible at NASA Planetary Data System, CO-SA-ISSNA-5-PHOEBESHAPE-V2.0. The file Phoebe_SH.dat presents a spherical harmonics decomposition of the phoebe_quad64q.tab DTM model. The Spherical Harmonics decomposition uses unnormalized Legendre polynomials. The uncertainties of each parameters are formal uncertainties coming from the covariance matrix. A more realistic uncertainty is about 0.5 km (see the paper). In order to minimize the degree 1 and off-diagonal degree 2 we translate the DTM by -0.4, 0.4, 0.4 km and rotate it by (0.62, 1.34, 91.98) degrees for the orientation angles with the rotation matrices in angular sequence 1,2,3.
