Notice:
People who use the redshift catalogues are strongly encouraged to
reference both the catalogue version and its accompanying description
(e.g. Huchra, J. Geller, M., Clemens, C., Tokarz, S and Michel, A.
1992, Bull. Inf. C.D.S. 41, 31) as well as original sources for the
galaxy redshifts as given in the file zsource.tex (or zsource.dat)
If you have any further questions (and are in dire need of answers),
address them to John Huchra
Description:
The catalog (files zcat.dat and zbig.dat) incorporates much of the
latest velocity data from the Whipple Observatory and other sources as
well as velocities from earlier compilations such as the Second
Reference Catalogue of de Vaucouleurs, de Vaucouleurs, and Corwin; the
Index of Galaxy Spectra of Gisler and Friel, and the Catalogue of
Radial Velocities of Galaxies of Palumbo, Tanzella-Nitti, and
Vettolani. The data included here are BT magnitudes and a few UGC
numbers with increased "accuracy" in the velocity source information.
The following separate tables contain selected objects
from the CfA Redshift Survey:
- the first CfA Redsdhift Survey (Huchra et al., 1983ApJS...52...89H 1983ApJS...52...89H);
this catalogue contains 2395 galaxies, a number slightly smaller
than the published number of 2399, since there have been small
corrections to the magnitudes for multiple galaxies. This version
has had new morphological types added by me as well as POSS
diameters measured for those galaxies that were not in the UGC or
did not have UGC diameters.
- the first slice of the second CfA redshift survey
(Huchra et al., 1990ApJS...72..433H 1990ApJS...72..433H)
- the second slice of the CfA redshift survey (Huchra et al.,
1995ApJS...99..391H 1995ApJS...99..391H)

Note on cfa2s2b.dat, cfa2s2f.dat:
the second slice (published in 1995ApJS...99..391H 1995ApJS...99..391H) comes in two
parts, the first part are the galaxies brighter than 15.5 (table1)
and the second are those that are fainter than 15.5 (table2).
