Top: average tangential ellipticity of the full satellite galaxy sample versus projected satellite distance from the group BGG, obtained using satellite shape – BGG position pairs. Results shown for different weight function sizes used in the shape measurement process. The r_wf indicates the size of the initial weight function and r_iso is the isophote of the galaxy. Bottom: amplitude of power-law fits with fixed exponent, to the average ellipticities for all, red and blue galaxies, for the different weight function sizes involved. Lines connecting the data points added for clarity.
