cds-question@unistra.frgalaxy-clustersgalaxiescatalogsredshiftedA "friends-of-friends" percolation algorithm has been used to extract a catalog of {delta}n/n=80 density enhancements (groups) from the six slices of the Las Campanas Redshift Survey (LCRS). The full catalog contains 1495 groups and includes 35% of the LCRS galaxy sample. A clean sample of 394 groups has been derived by culling groups from the full sample that either are too close to a slice edge, have a crossing time greater than a Hubble time, have a corrected velocity dispersion of zero, or contain a 55"-'orphan' (a galaxy with a mock redshift that was excluded from the original LCRS redshift catalog due to its proximity to another galaxy, i.e., within 55").2000ApJS..130..237Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/130/237CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/203 : Las Campanas Redshift
