The evolution of the relative fractions of categories. The different curves represent the different categories: accurate (solid, black curves), preservation (dashed, red curves) and exchange (dotted, blue curves). These three categories are defined in the text. From left to right, the data are from the Plummer, Plummer with different masses, cold Plummer and cold Plummer with different masses data sets. In the top panels we show the results for a Hermite time-step parameter \(\eta=2^{-11}\) and in the bottom for \(\eta= 2^{-3}\).
