Bacterial orientation as a function of applied shear. a, b Distributions of the in-plane angle ψ and the pitch angle θ, respectively, obtained by simulating N = 104 trajectories over long times until steady state is reached, for different shear rates \(\dot \gamma\). The parameters used are the same as in Fig. 1. Inset: same on a logarithmic scale. c, d Rheotaxis phase diagrams. Shown are the equilibrium in-plane angle ψ* and the equilibrium pitch angle θ*, respectively, obtained numerically from the full deterministic model (solid lines), analytically (dashed lines), from simulations (points) and from experiments (magenta stars). The four regimes (blue and white areas) are separated by critical shear rates \(\dot \gamma _c\)
