Average tangential ellipticity against projected satellite distance from the group BGG, obtained using satellite shape – BGG position pairs. Results shown for red, low sSFR and blue, high sSFR galaxies. Power-law fits of fixed index are overplotted, with the shaded region indicating the 1-σ confidence limit. The grey area covers the radial bins over which we regard the BGG light correction to be too significant, and these scales are not used for our model fitting.
