Distribution of the mean absolute magnitudes per bin of redshift. Only sources for which both B and I absolute magnitudes were determined are considered to the mean. Also shown is the same distribution as for the sources in the earlier version LQAC2 – that is, without the SDSS BOSS sources – and no net variation appears. The interesting asymmetry between the B and I distributions after redshift 5 must be taken with caution owing to the small number of elements in those bins. Symbols are slightly offset but refer to the same redshift bin.
