(a) Blue/black sites show regions of positive/negative vorticity, measured in monolayer of wild-type P. aeruginosa using PTV (Materials and Methods). (b) The intersection of zero-vorticity contour (shown in red) with a horizontal line. (c) The labeled zero-vorticity contour is mapped to the upper half-plane.
