摘要
We present 865 redshifts of galaxies located in the equatorial strip - 17.5-degrees less-than-or-equal-to delta less-than-or-equal-to - 2.5-degrees in the right ascension range 20h less-than-or-equal-to a less-than-or-equal-to 5h. Redshifts have been obtained for the complete sample of all 833 galaxies in the Morphological Catalog of Galaxies with magnitudes brighter than m = 14.5 (corresponding approximately to m(Zwicky) = 15.0). This sample also includes three galaxies from other sources with more reliable magnitudes, satisfying this limit, and 29 fainter galaxies, usually companions of the galaxies in the magnitude limited sample. Our maps of a very large volume of nearby space demonstrate a variety of coherent large scale structures which include large voids, 20-50h-1 Mpc in diameter and large walls at least 70h-1 Mpc across.
