Dimensionless tidal deformability parameters, denoted as Λ₁ and Λ₂, derived from the binary NS merger of the GW170817 event. These values were evaluated based on all 21 RMF EOSs, taking into account the observed chirp mass M_chirp = 1.186 M_⊙. The orange line (solid for 90% confidence and dashed for 50% confidence) indicates the confidence intervals, while the blue shaded area highlights the marginalized posterior derived from a parameterized EOS. This EOS has a maximum mass stipulation of 1.97 M_⊙, and within this blue region, the solid and dashed lines again depict 90% and 50% confidence intervals, respectively.
