Comparison of fitted values using different parameterizations/priors. We show the fitted eccentricity, e (left panels), argument of periastron ω (middle panels), and impact parameter b (right panels) of each planet. In the x-axis we denote the used method: the (f_s,f_c) parametrization, fixing the eccentricity to zero (e = 0) and by jumping directly on e and ω (e,ω). We also show the resulting values of the modeling with Allesfiter code (A).
