Notes. The merger ratio shows what percentage of mergers is produced per spectral type. All values are shown for both threshold period masses, mthr: 2 M⊙ and 5 M⊙. In the case of B-type stars and mthr = 5 M0, the first column shows that 3.53% of all stars at 0 Myr were B-type stars. The second column shows stars involved in merger events (pre-mergers) and out of those there are 48.15% B-type stars. 50.48% of the merger products are of spectral type B. Finally, the last column shows that 12.54% of all B-type stars (calculated from the number of B-type stars at a time of 0 Myr) end up as merger products.
