Detailed Description of J/ApJS/121/287 :
The CfA2S catalog (Huchra+, 1999)

XMM logo

Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

Abstract:
    We present redshifts for a sample of 4391 galaxies with magnitude
    mB(0)<=15.5 covering 20h<=RA<=4h in right ascension and
    -2.5°<=DE<=90° in declination. This sample is complete for all
    galaxies in the merge of the Zwicky et al. and Nilson catalogs in the
    south Galactic cap. Redshifts for 2964 of these were measured as part
    of the second CfA Redshift Survey. The data reveal large voids in the
    foreground and background of the Perseus-Pisces Supercluster. The
    largest of these voids lies at a mean velocity ~8000km/s, has diameter
    ~5000km/s, and is enclosed by a complex of dense structures. The large
    structure known as the Perseus-Pisces Supercluster forms the near side
    of this complex. On the far side of this large void, at a mean
    velocity ~12000km/s, there is another coherent dense wall. The
    structures in this survey support the view that galaxies generally lie
    on surfaces surrounding or nearly surrounding low-density regions or
    voids.
