Number of models in four mass bins (dN/ dM_{∗ ,fin}) and the calculation of the weight coefficients for the model IMF. The vertical dash-dotted lines outline the four bins, in which the final stellar masses (M_{∗ ,fin}) are divided. The solid line presents the Kroupa IMF normalized to the total number of our models. The open squares and circles are the values of the model IMF before and after weighing, respectively, and the numbers provide the weight coefficients ω_i.
