Experimental swarming traits of P. aeruginosa and its hyperswarmer mutant

Strain	Growth rate r (measured in Deforet et al. (2015))	Expansion rate v (measured in Deforet et al. (2014))	Diffusion rate D (calculated)	Decay length λ (calculated)
Wild-type	1.1 ± 0.05h−1	3.0 ± 0.1mm/h	2.0 ± 0.15mm2/h	1.4 ± 0.07mm
Hyperswarmer	1.0 ± 0.04h−1	4.0 ± 0.15mm/h	4.0 ± 0.27mm2/h	2.0 ± 0.11mm

Note: Errors are standard deviations. Errors on calculated parameters are inferred from the formula of propagation of errors.
