Notes. Uncertainties are noted in parentheses for values calculated in this work and when given for values taken from the literature. Milky Way extinction corrections were performed using Rv = 3.1, with E(B-V) values through querying the IRSA dust maps (Schlegel et al. 1998).*Calculated from the redshift measurement with H0 = 70.3 km s−1 Mpc (Hotokezaka et al. 2019).
