 2. Compute the same for inter-binsin.dat file and plot both results on the same plot (with anything). These events from inter-binsin.dat should be smaller.

 3. Plot, on the same figure, the results from the 1. and 2. points. You will see when the primordial BHs merge (point 1.) and the dynamical BHs are merging (point 2.).
