Left figure: residuals (R_SP − R_LEG) between the radius of each of the 66 stars in the Kepler LEGACY sample delivered by SPInS (R_SP) and the values R_LEG obtained from full optimisations of stellar models based on their individual oscillation frequencies by different pipelines (see e.g. Silva Aguirre et al. 2017). Right figure: same comparisons for the mass. SPInS inference is based on observational constraints on T_eff, [Fe/H], log g, ⟨Δν⟩, and ν_max. The position of KIC 7771282, as modelled by the GOE pipeline is the pink diamond outlier at R_SP ≈  1.66 R_⊙ (R_LEG, GOE ≈ 1.4 R_⊙) and M_SP ≈  1.3 M_⊙ (M_LEG, GOE ≈ 0.8 M_⊙). Symbol colours and shapes identify the pipelines as explained in the legend.
