Python tools for obtaining and working with model synthetic spherical harmonic coefficients for comparing with data from the NASA/DLR GRACE and NASA/GFZ GRACE Follow-on missions

Python tools for obtaining and working with model synthetic spherical harmonic coefficients for comparing with data from the the NASA/DLR Gravity Recovery and Climate Experiment (GRACE) and the NASA/GFZ Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) missions

These are extension routines for the set of gravity-toolkit tools
