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 ...
