Sky and redshift distribution

We illustrate in Fig. 5a the sky distribution of all our observed ELGs (filled circles) in comparison with the distribution of all other observed ELGs in the same zone (open circles). Our ELGs comprise the majority of all Case emission-line galaxies in the upper half of the lane $\delta$= $29^{\circ}$ - $38^{\circ}$, and the most of ELGs in this lane at $\alpha \gt 13^h$.The hole near $\alpha = 14^h$ is partly due to the field coverage in the Case survey, and partly due to the absence in this region of Case galaxies which have in the catalog any code of [OIII] emission line strength.

The redshift distribution of our ELGs is shown in Fig. 5b (solid line) in comparison with the same distribution for all other Case ELG in this zone (dashed line). Both distributions look very similar, with abrupt decline of the number of ELGs for z > 0.04. A few ELGs are at redshifts z > 0.06. This redshift distribution looks very similar to that of BCGs in the zone of the SBS (Pustilnik et al. [1995]).
