J/ApJ/306/30       Catalog of distant galaxy clusters        (Gunn+, 1986)

A systematic survey for distant galaxy clusters. Gunn J.E., Hoessel J.G., Oke J.B. <Astrophys. J. 306, 30 (1986)> =1986ApJ...306...30G
ADC_Keywords: Clusters, galaxy ; Positional data Keywords: cosmology - galaxies : clustering - galaxies : photometry Abstract: A photographic survey for faint galaxies has been carried out with fine-grained photographic emulsions using the 1.2m Schmidt and 5m Hale telescopes, as well as the 4m Mayall telescope. A total of 418 clusters have been found with redshifts mostly in the range from 0.15 to 0.92. The survey was planned to minimize distance-dependent selection effects in the resulting catalog. In areas of sky where the deepest search was made, the sample is complete to about z=0.50; there are 11 clusters per square degree at this limit. At a redshift of 1.0 there should be 63 or 45 clusters per square degree depending on whether q0 is 0.0 or 0.5, provided there is no evolution. File Summary:

Note (1): Type of observation as follows: HF = Cluster found in the Hale telescope survey MF = Cluster photographied at the prime focus on the Mayall 4m telescope MN = Cluster photographied at the prime focus on the Mayall 4m telescope using silver nitrate-hypersensitized IV-N plates and an RG 695 filter. SF = Cluster found in Schmidt IIIa-F plate SJ = Cluster found in Schmidt IIIa-J plate
Nomenclature Notes: The clusters are identified as GHO HHMMSS+DDMMSS in Simbad History: Prepared via OCR at CDS.
