"name": "This is Figure 3 of the paper. It shows, drawn in black against a white background, and with our location marked by a bullet at center, numerous concentric arcs, having our location as center, and distributed with a density that varies radially and transversally. A subset of these arcs represents the background density field, while another subset represents the large scale clustering of matter. A caption reads as follows: \"A possible distribution of large scale clusters as seen by an observer at the centre. The contrast between clusters and the background would be less marked in the past (though the mean density was then higher) because the clusters would not have fully separated out. The shading is meant to illustrate this. Very remote objects (for example, radio sources) need not therefore appear anisotropically distributed.\"",
