Cumulative PA distributions of edge-on galaxies with respect to the supergalactic plane. The panels show the distributions within the cz_LG < 1200 and cz_LG < 2400 km s⁻¹ ranges for subsamples of the bright and faint galaxies, separated by stellar mass at M_* = 10^8.7 M_⊙, as well as for the blue and red galaxies, divided by color at (g − i)₀ = 0.86 mag. The top row corresponds to the ±2 Mpc layer relative to the supergalactic plane, and the bottom row shows the distributions within the ±5 Mpc layer. The virial zone of the Virgo cluster was excluded from our consideration. The dashed black line indicates the uniform distribution.
