Dependence on density profile steepness p of a) the maximum sausage period P_max and b) the threshold length-to-radius ratio (L/a)_cutoff. The black (red) curves are for loops described by profile E (N). A density contrast of 25 is adopted. The solid curves corresponds to the static case (flow magnitude U₀ = 0), while the dotted and dashed lines correspond to the cases with flow where the flow profile steepness u is 1.1 and 100, respectively. In the cases with flow, U₀ is fixed at 0.08 v_A∞.
