Histogram of orbital separation at birth time and at 200 Myr (cluster with mass segregation S = 0 and 1). The black line, blue line, and red dashed line represent the orbital separation for the two clusters with mean property parameters (corresponding to the lines in Fig. 5), and the dash-dotted lines refer to the mode values of orbital separations for clusters fitted with a gamma function. The dotted lines refer to the median values of orbital separations for clusters with MCMC sampling parameters. The dash-dotted lines represent the mode values from the gamma fitting of the density distributions.
