Notes. pretrograde is the fraction of MCMC simulations that end up with an opposite sense of rotation with respect to the pre-SN orbit. frunaway is the expected fraction of unbound systems assuming a random direction of the same inferred NS kick for each MCMC simulation. The higher this fraction, the less likely it is that such a system is found as a survival binary in an HMXB phase. Ppre-SN and Mpre-SN are respectively the inferred pre-SN orbital period and the pre-SN progenitor mass, assuming a NS mass of 1.4 M⊙ and a uniform prior in the 1.4−10 M⊙ mass range. w is the magnitude of the kick experienced by the NS after the SN event.
