Solid lines from top-to-bottom. Kroupa (2001)A1 and Kroupa (2001)B¹ IMFs produce model evolutionary tracks that overlap with one another. The rest of the evolutionary tracks are generated by using Scalo (1998), Kennicutt (1983), Kroupa et al. (1993) and Miller & Scalo (1979) IMFs. The dashed lines represent the three evolutionary model tracks from previous figures.
