Fig. 9


Propagated formal errors in position components over the observational period (panel a: Io, panel b: Europa). The errors in position are expressed in the RSW frame (see Fig. 2) and are obtained from the propagated covariance matrix and estimated initial states. The purple dots (right axis) display the ratio between the normalised contributions of central instants over their corresponding alternative observables, for each mutual approximation.
