Corresponding Dataset for Gravity Field of Ganymede after the Juno Extended Mission

Corresponding Dataset for Gravity Field of Ganymede after the Juno Extended Mission Luis Gomez Casajus August 2, 2022 ============================================================================= Introduction ============================================================================= This dataset contains the estimated gravity field and its corresponding full covariance matrix. This dataset is provided in order to supplement the submitted article to the "Geophysical Research Letters" journal: Gravity Field of Ganymede after the Juno Extended Mission. L. Gomez Casajus (*), A. I. Ermakov, M. Zannoni, J. T. Keane, D. Stevenson, D. R.Buccino, D. Durante, M. Parisi, R. S. Park, P. Tortora and S. J. Bolton - (*) [e-mail] ============================================================================= File description ============================================================================= This archive contains two files within the root directory. ROOT -SOI_gravity_field.txt This file contains the estimated normalized spherical harmonics coefficients of the Ganymede gravity field. The file contains a header row which provides a description of the file. -SOI_cov_matrix.txt This file contains the estimated full covariance matrix (32x32) of the normalized spherical harmonics coefficients of the Ganymede gravity field. The file contains a header row which provides a description of the file. The matrix is represented as a 2 dimensional array whose coefficients follow the following order scheme: C20 C21 S21 C22 S22 C30 C31 ... ============================================================================= ACKNOWLEDGMENTS ============================================================================= The authors are grateful to William Folkner, to the entire Solar System Dynamics Group and to Robert Haw, former Galileo navigator, for the useful discussions and suggestions regarding the procedures for Galileo data analysis.
