Posterior distributions without SEP violation. Yellow: Posterior distribution for 1 − γ without the implementation of the SEP violation. Green: Absolute value of the simulated posterior for the determination of 1 − γ with Cassini. Red line (dot-dashed): 99.7% C.L. ((1 − γ) = 2.50 × 10⁻⁵). Blue line (dotted): 66.7% C.L. ((1 − γ) = 1.73 × 10⁻⁵). Purple line (dashed): 95% C.L. ((1 − γ) = 2.40 × 10⁻⁵). The prior for (1 − γ) is a uniform prior between 0 and 15 × 10⁻⁵. Solid black line: Absolute value of Cassini central value estimation ((1 − γ) = −2.1 × 10⁻⁵). Dashed black line: Upper bound estimation from Cassini at 1σ C.L.
