as a function of the radius of the more massive component, R(M₁) for the low-spin estimation of parameters of the GW170817 event. Squares denote the lowest estimated mass of the primary component, M₁ = 1.36 M_⊙, while triangles denote the highest mass, M₁ = 1.6 M_⊙. The dashed line corresponds to the fit by Raithel et al. (2018). The thick dotted line indicates the 90% confidence limit of 900 for (corrected value from Abbott et al. 2019, Table IV). Information about varying with the mass ratio q = M₂/M₁ for fixed chirp mass is encoded in the plot: curves for selected EOS follow the fixed chirp mass of GW170817. The square denotes the M₁ = 1.36 M_⊙ (i.e. M₁ = M₂, q = 1), while the triangle denotes M₁ = 1.60 M_⊙ (M₂ = 1.17 M_⊙, q = 0.725).
