Fig. 3.
Mean tangential/cross ellipticity (red/gray points) versus projected satellite distance from the group’s BGG, obtained using satellite shape – BGG position pairs. Positive values of ⟨ϵ+⟩ indicate radial alignment while randomly oriented galaxies exhibit ⟨ϵ+⟩=0. Results shown for shape measurements obtained from r-band images, with rwf = riso.
