fBm map with ζ = 3 (left panel) and the same map after displacing all structures on scales l ≥ 10 pix by τi,x = 10 pix and τi,y = −15 pix (right panel). This pair is to mimic an interstellar cloud structure that could be created by the superposition of small scale turbulence and a large scale velocity gradient.
