Fits of Eq. 4 to the experimental distribution of velocity changes \(\Delta {{\textbf {v}}}\) for ants in the arena interior. Left: the distribution \(p(\Delta v_T)\) for the component \(\Delta v_T\) of \(\Delta {{\textbf {v}}}\) that is perpendicular to velocity. The insets show the standard deviation σT and mean \(\Delta v_T\) as a function of speed: the latter always zero. Right: \(p(\Delta v_L)\) for the component \(\Delta v_L\) of velocity change parallel to velocity. The insets show the standard deviation σL and mean of \(\Delta v_L\) versus speed and their linear fits. Most data falls within the range of speed where this linear approximation is roughly valid
