Normalised pair surface density ${\widehat{\text{Σ}}}_{\text{pairs }}$ as a function of projected separation ∆R in parsecs. The red line shows the observed surface density for Taurus from the Luhman (2023) census, which may be incomplete at the smallest separations. The coloured lines show the outcome from our model, at snapshot outputs indicated by the colour bar. The 1 Myr snapshot is also marked by black crosses, at which time the pair distribution function is in good agreement between observations and simulation.
