Projected spatial distribution and 2D-DEDICA isodensity contours of SDSS galaxies with | (r − i) − (r − i)_BCG | ≤ 0.2 and M_r< − 19 in a few FGSs spanning a wide range of appearances (see text). The plots are centered on the S07 BCGs (marked with black crosses). The inner circle encloses the region within R₂₀₀. The outer two circles enclose the regions within 2R₂₀₀ and 3R₂₀₀. The sectors used for the computation of the local field are displayed. Units on the axes are in Mpc.
