Abstract:
     The Las Campanas Redshift Survey (LCRS) consists of 26,418
  redshifts of galaxies selected from a CCD-based catalog obtained in
  the R band.  The survey covers over 700 deg^2 in six strips, each
  1.5x80 deg, three each in the north and south Galactic caps.  The
  median redshift in the survey is about 30,000 km/s.  Essential
  features of the galaxy selection and redshift measurement methods are
  described and tabulated here.  These details are important for
  subsequent analysis of the LCRS data.  Two-dimensional representations
  of the redshift distributions reveal many repititions of voids, on the
  scale of about 5000 km/s, sharply bounded by large walls of galaxies
  as seen in nearby surveys.  Statistical investigations of the mean
  galaxy properties and of clustering on the large scale are reported
  elsewhere.  These include studies of the luminosity function, power
  spectrum in two and three dimensions, correlation function, pairwise
  velocity distribution, identification of large-scale structures, and a
  group catalog.  The LCRS redshift catalog will be made available to
  interested investigators at an internet web site and in archival form
  as an AAS CD-ROM.

Description:
  For each of the 327 fields in the Las Campanas Redshift Survey (LCRS)
  proper, there is one ascii table which catalogs the photometric and
  spectroscopic information for that field. The tables are named
  "1003_12w.cat", etc., where "1003" denotes RA, "_12" denotes DEC where
  the underscore character "_" has replaced a minus sign "-" in the names
  on the CD-ROM (minus signs are illegal characters in ISO 9660 CD-ROM
  file names), and "W", "E", or "M" means west, east, or middle,
  respectively. 

  See the author-supplied file, readme.doc, for a thorough discussion of
  the format of the LCRS data files.
