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 huchra@cfa.harvard.edu

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);
      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)

    - the second slice of the CfA redshift survey (Huchra et al.,
      1995ApJS...99..391H)

Note on cfa2s2b.dat, cfa2s2f.dat:
     the second slice (published in 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).
