Map of , corresponding to the dressed secular diffusion flux, using the same conventions as in Fig. 4. In order to limit ourselves only to tightly wound contributions, the basis elements associated with the radial basis index n ∈ {0,1 } have not been taken into account. The contours are spaced linearly between the minimum and the maximum of . The maximum value for the positive blue contours corresponds to , while the minimum for the negative red contours is associated with . This figure is to be compared to Fig. 9 of Paper I.
