The y-axis is the quotient (see Sect. 3.4) value for the subsamples of filamentary spines dependent on the distance r, which is described by the x-axis. The dark green line draws the distance quotients for all filamentary spines to the photometric galaxy lines of sight. The dark blue line draws the distance quotients for the perpendicular filamentary spines to the photometric galaxy lines of sight. The orange line draws the same quotient for non-perpendicular filamentary spines and photometric galaxy lines of sight. The shaded areas surrounding the lines denote the calculated 0.95 confidence intervals.
