Characteristic scales from the phase for n = −2. The scaling of characteristic wavenumber scales, k_c vs. a is shown, as derived from the mean phase deviation; k_c(a, φ_c) is the value of k at which ⟨ | δφ(k, a) |⟩ = φ_c. The four solid curves correspond to the values of φ_c labeled at the top of the plot. Note that for high values of φ_c (top two curves), the scaling closely agrees with k_c ∝ a⁻¹, shown by the upper dotted line. A transition toward the standard self‐similar scaling k_c ∝ a⁻², shown by the lower dotted line, occurs for the two lower values of φ_c.
