Marginalized posterior of the astrophysical observables shown in Fig. 2 for Set A (top row) and Set B (bottom row). We show the results for the posterior without any assumption on the dUrca threshold (solid black line) as well as those including the three assumptions on the threshold Always (M_dUrca < 1.3 M_⊙), Sometimes (1.3 M_⊙ ≤ M_dUrca ≤ 2.1 M_⊙), and Never (M_dUrca > 2.1 M_⊙) (dotted blue line, dashed orange line, and dash-dotted green line, respectively).
