Angle a_fil between the projected velocity of a halo (v_rad, C) and the local direction of the closest filament as a function of the halo distance from the axis of the filaments d_fil. Points represent the actual measurements, solid lines represent the running means of a_fil as a function of d_fil, error bars encompass the region between the 16th and the 84th percentile of the distributions. Different panels refer to different combinations of DisPerSE parameters and galaxy selections.
