VII/193 The CfA Redshift Catalogue, Version June 1995 (Huchra+ 1995)
The CfA Redshift Catalogue, Version June 1995 Huchra J.P., Geller M.J., Clemens C.M., Tokarz S.P., Michel A. <Harvard-Smithsonian Center for Astrophysics (1995)>
ADC_Keywords: Redshifts 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); 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) See the complete description in 'zcom.tex' (in plain TeX), or zcom.txt (plain ascii) File Summary:

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).
