A Complete Redshift Survey to the Zwicky Catalog Limit in a 2h × 15° Region around 3C 273

We compile 1113 redshifts (648 new measurements, 465 from the literature) for Zwicky catalog galaxies in the region (-3.°5 ≤ δ ≤ 8.°5, 11.ͪ5 ≤ α ≤ 13.ͪ5). We include redshifts for 114 component objects in 78 Zwicky catalog multiplets. The redshift survey in this region is 99.5% complete to the Zwicky catalog limit, mZw = 15.7. It is 99.9% complete to mZw = 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 catalog, bright and faint galaxies trace the same large-scale structure.
