Bar chart representation of values in Table 3. The solid boxes represent the analysis of simulations with a threshold mass of 2 M_⊙. The hatched boxes represent simulations with a threshold mass of 5 M_⊙. The grey bars demonstrate all stars at a time of 0 Myr, the cyan colour stands for the initial spectral type distribution of stars that are involved in merger events, blue represents spectral types of the merger products, and the orange colour shows the ratio of mergers for each spectral type.
