THE LAS-CAMPANAS REDSHIFT SURVEY

The Las Campanas Redshift Survey (LCRS) consists of 26,418 redshifts o f galaxies selected from a CCD-based catalog obtained in the R band. T he survey covers over 700 deg(2) in six strips, each 1.degrees 5 x 80 degrees, three each in the north and south Galactic caps. The median r edshift in the survey is about 30,000 km s(-1). Essential features of the galaxy selection and redshift measurement methods are described an d tabulated here. These details are important for subsequent analysis of the LCRS data, Two-dimensional representations of the redshift dist ributions reveal many repetitions of voids, on the scale of about 5000 km s(-1), sharply bounded by large walls of galaxies as seen in nearb y surveys. Statistical investigations of the mean galaxy properties an d of clustering on the large scale are reported elsewhere. These inclu de studies of the luminosity function, power spectrum in two and three dimensions, correlation function, pairwise velocity distribution, ide ntification of large-scale structures, and a group catalog. The LCRS r edshift catalog will be made available to interested investigators at an internet web site and in archival form as an AAS CD-ROM.
