Left: distribution of distances for the 245 sources of our sample. Redshift-independent distances (Steer et al. 2017) are reported in the foreground (dashed histogram), while in the background (blue filled histogram) we report all adopted distances, including those that are model-corrected. The vertical dashed line shows the Virgo cluster distance, while the gray vertical rectangle corresponds to the ±r₂₀₀ region. Right: scatter plot with model-corrected distances (y-axis) vs. redshift-independent distances (x-axis). Red points refer to our sample of 245 filament galaxies, gray points refer to galaxies in the field of Virgo at distances in the range ∼(0–60) Mpc. The solid black line shows the one-to-one relation, while the dashed lines correspond to an rms = 0.1 dex.
