VII/56 Redshifts for Abell Clusters (Sarazin+ 1982)
================================================================================
A Table of redshifts for Abell Clusters
Sarazin C.L., Rood H.J., Struble M.F.
<Astron. Astrophys. 108, L7 (1982)>
=1982A&A...108L...7S
================================================================================
ADC_Keywords: Redshifts ; Clusters, galaxy
Description:
The catalog gives redshifts for 329 Abell clusters, all those known to
the authors in published or preprint form at the time of the
compilation (through 1982). The data table has been compiled
critically, based partially on a number of photometric distance
estimators derived from the redshift data. These were used to evaluate
probable accuracies of the redshifts and to resolve discrepancies
among different values for the same clusters. The catalog includes
Abell (1958) cluster numbers, redshifts, and the number of redshifts
of different galaxies averaged to determine the cluster value. The
machine version was prepared at the Astronomical Data Center,
NASA/GSFC.
Note that Struble and Rood published further compilations in 1987
(1987ApJS...63..543S) and 1991 (1991ApJS...77..363S).
Other redshift compilations are also available in electronic form
(see "See also" section below).

Historical Notes:
* November 1983 (Wayne H. Warren Jr., NSSDC/WDC-A-R&S 83-18):
The data and notes files of A Table of Redshifts for Abell Clusters
were created at the Astronomical Data Center by keying the data
directly to a computer disk. The data were listed, checked against the
source reference, and transferred to magnetic tape.
* December 1995: Documentation standardized at CDS (Francois Ochsenbein)
Acknowledgements:
Appreciation is extended to the authors for permission to make these
data machine-readable and to distribute the catalog to the
astronomical community. They have also reviewed the document prior to
final printing.
