Normalized distribution of the best-fitting values obtained from injection tests performed for the planetary eclipse (top) and for the phase modulation (bottom). The synthetic eclipse depth has been set to 5 ppm and thephase modulation amplitude to α₁₃ = 48.3 ppm. Bottom right panel: the difference between the inputs and estimates of the phase parameter (ΔΦ₁₃) as the inputphase value is randomly changing from one test to another.
