Recovered Petrosian flux to input S rsic flux as a function of the separation of the two galaxies in the pair. We show both LRG and small galaxy whose radius is only 80% of that of LRG. The vertical line shows the smallest separation in our research at z = 0.15 and r _p = 14.9  h ⁻¹ ₇₀ kpc. For LRG, on average there is an excess in the recovered flux of galaxies separated by less than 20 arcsec.
