Fig. 1


Left panel: logarithm of the [O III] emission line flux (in units of 10-17   erg   s-1   cm-2) versus the k-corrected i band magnitude within the SDSS fiber, both quantities corrected for galactic absorption. Green dots mark upper limits in line flux. The dashed red line corresponds to a constant ratio between the two quantities. Contours (blue for the objects with an [O III] detection, yellow for upper limits) represent the iso-densities of DR7 galaxies in the same redshift range; levels are in geometric sequence with a common ratio of 4. Right panel: histogram of the residuals from the median line. The dashed histogram is the contribution of upper limits. The dispersion of the distribution is 0.18 dex. Bottom: residuals from the median vs. redshift.
