A Complete Redshift Survey to the Zwicky Catalog Limit in a 2-hour by 15-degree Region Around 3C 273

Abstract

We compile 1113 redshifts (648 new measurements, 465 from the literature) for Zwicky catalogue galaxies in the region (-3.5deg < δ< 8.5deg, 11.5h < α< 13.5h). We include redshifts for 114 component objects in 78 Zwicky catalogue multiplets. The redshift survey in this region is 99.5% complete to the Zwicky catalogue limit, m_Zw=15.7. It is 99.9% complete to m_Zw = 15.5, the CfA Redshift Survey (CfA2) magnitude limit. The survey region is adjacent to the northern portion of CfA2, overlaps the northernmost slice of the Las Campanas Redshift Survey, includes the southern extent of the Virgo Cluster, and is roughly centered on the QSO 3C 273. As in other portions of the Zwicky catalogue, bright and faint galaxies trace the same large-scale structure.
