Spatial distribution of the KISS ELGs. The CGCG comparison sample is displayed as dots, while the ELGs are larger, open circles. (a) Velocities plotted out to 15,000 km s−1. The ELGs are seen to trace the large‐scale structures defined by the CGCG galaxies at low redshift. However, they exhibit the appearance of being less tightly clustered. A large number of ELGs are seen to fall in voids. (b) Velocities plotted out to 30,000 km s−1. At larger distances, the ELGs appear to reveal several structures not visible in the shallower CfA2 redshift catalog. The number of ELGs remains high out to ~27,000 km s−1, the point at which the filter used for the survey truncates the sample. The lack of objects in the ELG distribution near 14h40m is caused by a 15m gap in the survey (see § 2).
