Properties of the colour-selected samples. ‘b’ stands for bright (20 < g < 22.5 for ugr or 19 < i < 21.3 for gri) and ‘f’ stands for faint (22.5 < g < 23.5 for ugr or 21.3 < i < 23 for gri). We indicate the mean and standard deviation of the redshift distribution for each set. For the CMC sample, [O ii] fluxes are expressed in units of 10−17 erg cm−2 s−1; the median, the first and third quartiles of the flux distribution are indicated. The ugr tends to select the highest [O ii] fluxes.
