Notes. The inputs we adopt from previous literature are marked in bold-faced text. For R144-primary and secondary components, we adopt the luminosities and the dynamical masses from Shenar et al. (2021). The surface H for R144 were also initially adopted from Shenar et al. (2021), but was later reduced by 0.1 to achieve better fits to H/He lines. For R136a1, the luminosities and surface H are adopted from Bestenlehner et al. (2020), and the masses are from homogeneous relations from Gräfener et al. (2011).
