contents <p><br>We analyse the reconstructed velocity field of the Cosmicflows-4 (CF4) compilation on a 64³<br>grid and quantify the kinematics of the local cosmic web. From the density contrast we derive<br>the gravitational potential, tidal tensor, velocity divergence and vorticity. We further study the<br>alignment of the velocity field with the intermediate eigenvector of the tidal tensor and analyse its<br>dependence on density contrast</p>
