Upper: expected mean number count in spheres (solid line, from Eq. (2)) with respect to the observed one (symbols) for the various luminosity cuts and for the three redshift bins [ 0.5,0.7 ] (left panel), [ 0.7,0.9 ] (central panel), and [ 0.9,1.1 ] (right panel). The selection in absolute magnitude M_B in B-band, corresponding to each symbols/lines and colors, are indicated in the inset. The dotted line displays the . Lower: deviation α (see Eq. (3)) between the expected mean number and the observed one with respect to the radius R of the cells.
