Comparing the simulated and measured distributions. The model parameters are \(\tau _D = 0.55\) s, \(v_0 = 6.3\) cm/s, \(\sigma _L = 1.25\) cm/s and \(\sigma _T = 1.00\) cm/s (the distance \(\ell\), and speeds \(v_s\) and width \(v_\infty\) are given in Eqs. 16, 21). Top left: the density n(x) versus position x (black symbols) and n(y) versus position y (red) of ants in the simulation (main panel) and experiment (inset). Top right: the distribution over velocity \(P(v_x)\) versus \(v_x\) (black) and \(P(v_y)\) versus \(v_y\) (red) in the simulation (main panel) and experiment (inset). Bottom: contour maps of \(P(v_x,v_y)\), with simulation in main panel and measurement in inset, for ants that are further than 3 cm from a boundary (left plot) or within 3 cm of a boundary (right plot)
