Normalised parameter distributions for clumps in snapshot 377, direction x and distance 231 pc (red histograms). The blue histograms show the corresponding distributions for PGCC sources with within 50% the same distance. The mean values of the parameters are shown for the PGCC catalogue (upper numbers in blue) and for the simulated catalogue (lower numbers in red). The first frame also shows the number of clumps included in the plots.
