PDF of ν_g1 = cos α_g1, the cosine of the angle between the minor axis of the central galaxy and the direction of the nearest filament, for three subsets of low-mass centrals (10⁹ < M_g < 10^10.25 M_⊙, upper threshold corresponds to the lower limit for the galactic plane orientation transition mass as estimated in Dubois et al. 2014) depending on the distance of their closest satellite: R_gs < 0.5 R_vir, 0.5 R_vir < R_gs < R_vir and R_gs > R_vir. The presence of a close satellite impacts the orientation of the central spin and damps its tendency to align to the nearest filament. The closer the satellite, the stronger the effect.
