	Figure 1: Schematic form of the linearized flow of the $s- l$ , $l ≥ 1$ , perturbations; $t = -1 ln μ∕μ 2π 0$ , $p ϱ = ρ$ .
	Figure 2: Flow pattern in the $g$ – $λ$ plane with a sharp mode cut-off. The arrows point in the direction of the coarse graining, i.e. of decreasing $k$ . (From [181].)
	Figure 3: Trajectory of the linearized flow equation obtained from the $R2$ -truncation for $− 1 ≥ t = ln(k0∕k) > − ∞$ . In the right panel we depict the eigendirections and the “box” to which the trajectory is confined. (From [132].)
	Figure 4: $g∗$ , $λ ∗$ , and $g∗λ∗$ as functions of $s$ for $1 ≤ s ≤ 5$ (left panel) and $ν∗$ as a function of $s$ for $1 ≤ s ≤ 30$ (right panel), using the family of exponential shape functions (4.51 ). (From [132].)
	Figure 5: $θ′ = − Re ϑ1$ and $θ′′ = − Im ϑ1$ (left panel) and $θ3 = − ϑ3$ (right panel) as functions of $s$ , using the family of exponential shape functions (4.51 ).
	Figure 6: Schematic view of the action flow in the vicinity of a (UV) fixed point. Shown is a typical flow line (black) and a renormalized trajectory (red) emanating from the fixed point. The arrows on the flow lines give the direction of the coarse graining, i.e. of decreasing $l$ or increasing $t$ .
