Notes. The number of PPS found are shown in Col. 6. Column 7 shows the expected number of IMXB in the LMC today, see Sect. 4.4. CO prescription refers to those given in Fryer et al. (2012), αCE is the CE efficiency parameter. We have used two SN kick velocity distributions. For the Maxwellian distribution σv is the most probable kick velocity and for the uniform distribution it refers to the upper kick limit. σv = 0 means no natal kicks imparted onto the BH.
