Fit of the TIC 323486857 system assuming the same core overshooting efficiency for all stars. Left: 2D kernel density estimator of the posterior distribution of the system parameters in the age vs. β plane. Right: Best fitting isochrone in the radius vs. effective temperature plane. The open dots indicate the derived system constraints, while the solid red and blue lines correspond to S1 and S2, respectively. The triangle identifies the position of the fitted tertiary star for S1.
