Hubble constant determination with prior distribution from GW190425. This figure follows the same panel structure as Fig. 21. The orange contour adds the constraint from a rebinned spectrum of 50 Å. The synthetic KN used to compute this plot assumes merger parameters consistent with GW190425 and EoS DD2 (run 3, see Table 1) a luminosity distance of 159 Mpc (z ∼ 0.035) and a inclination angle of ∼40°. Note that gri prior is computed for a survey with depth ∼22 mag while the MAAT 50 Å prior comes from a rebinning of the observed MAAT spectra, which improves S/N.
