Initial distribution of masses (upper panels) and total energy (lower panels) with respect to the three-dimensional radial position of a star in the cluster. Three primordial mass segregations of our models containing 52 stars are shown: seg and Šubr are initially mass segregated with S = 1 and S = 0.5, respectively, and non is without any initial mass segregation (S = 0), see Sect. 2. The light crosses represent one realisation, and the darker lines are averages from all realisations.
