Notes. We use a Kroupa ’93 (Kroupa et al. 1993), a Kroupa ’01 (Kroupa 2001), a Salpeter (Salpeter 1955), and two simple powe-law (PL) mass functions with slopes α = −2.5 and −2.4. For each IMF we use three different values for the metallicity (Z), 0.0001, 0.001, and 0.02, and we create 100 realisations for each IMF-Z combination. We then evolve the stars up to 10 Myr using the stellar evolution code sse. Finally, we find averages for the number of BHs (third column) and their minimum (fourth column) and maximum (fifth column) masses. In all data sets the total number of stars is 32768 and their initial masses range from 0.2 M⊙ to 150 M⊙.
