Histogram of the redshifts of the 149 BCGs in our sample. The red histogram shows all the BCGs studied, while the blue histogram (37 BCGs) shows those observed in rest frame filters that are too blue compared to the 4000 Å break (see Sect. 3). The green histogram (25 BCGs) shows all BCGs with an important inner component (see Sect. 4).
