Projections of maximum visit map values in slices obtained from the Bisous model using different samples. Only a smaller 100 Mpc × 100 Mpc area is shown for visual clarity. The thickness of the slice is 10 Mpc. Usually, a visit map limit of 0.05 is used to classify whether or not a coordinate is inside a filament. Therefore, everything besides the blue area is likely part of the filamentary network. The vertical axis (z) is parallel to the axis of the photometric uncertainties, i.e., it emulates the line of sight. The leftmost column shows samples with only photometric galaxies, the middle column shows mixed samples with medium uncertainties (σ = 5 Mpc) for photometric galaxies, and the rightmost column shows mixed samples with the larger uncertainties (σ = 10 Mpc). Different rows in the leftmost column have different photometric uncertainties, and the middle and the rightmost column have different fractions of the brightest galaxies as spectroscopic galaxies. See Table 1 and Sect. 2.3 for the sample naming convention used here.
