The first 20 zonal spherical harmonic shapes on Jupiter
The goal of gravity science on the Juno mission is to figure out a list of constants to multiply these shapes by in order to best approximate the shape of Jupiter's gravity field.

Spherical harmonic coefficients for Jupiter's gravity field as measured by Juno during its first few Jupiter flybys
Each coefficient should be divided by 10^6. Over the course of the Juno mission, more of these coefficients will be measured, and precision increased.
