Note that out of the 421 reliable redshifts that we obtained, 39 were
those of stars misclassified as galaxies in our photometric plate
catalogue. In order to show that most misclassifications were made on
faint objects, we show in Figs. 15 (click here) and 17 (click here) the
magnitude histograms for the galaxies with measured velocities and
those for the 39 stars. Although this number may seem large, it
corresponds to a percentage of contamination only 5% for 
, in agreement with the verification made by eye on a portion of
the catalogue. The contamination by foreground and background
galaxies is illustrated in Fig. 16 (click here), which shows the histogram
of the R magnitudes for the galaxies outside the velocity range
13350-2000 kms corresponding to ABCG85.

velocities
The coordinates (equinox 2000.0) of the 39 stars misclassified as galaxies are given in Table 3 (click here), to avoid further observations of these objects in galaxy surveys.

The velocity data for the galaxies in the field of ABCG 85 are given
in Table 4 (available in electronic form only). The signification of the
columns is the following:
(1) Running number;
(2) to (4): right ascension (equinox 2000.0);
(5) to (7): declination (equinox 2000.0);
(8): heliocentric velocity (cz) in kms-1;
(9): error on the velocity in kms-1; for velocities derived from absorption
lines, the error is either that stated in the literature or, for our own
measurements, that given by the RVSAO IRAF package; for velocities derived
from several emission lines, the error was estimated from the dispersion
between the velocities derived from the different emission lines; when
only one emission line was present and an absorption line redshift was
obtainable, the error on the velocity was taken to be the dispersion
between both measurements; finally, when only one emission line was present
and no absorption line redshift was available, the error on the velocity
was taken to be the mean internal velocity error;
(10): Tonry & Davis R parameter;
(11): label indicating the means of determination of the redshift: 0 = derived
from absorption lines, 1 = derived from emission lines;
(12): label indicating the quality of the data, from 1 (best) to 3 (0 for
data taken from the literature);
(13): label indicating the origin of the data: 1 = Malumuth et al. (1992),
2 = Beers et al. (1991), 3 = our data;
(14) and (15): X and Y positions in arcseconds relative to the center
assumed to have coordinates
(equinox 2000.0);
(16) distance to the cluster center in arcseconds;
(17) to (19): magnitudes in the b
, V and R bands respectively;
(20): reference to the galaxy number in the Beers et al. (1991) (B) and
Malumuth et al. (1992) (M) catalogues, as well as reference to the name given
to six galaxies identified as X-ray sources by Pislar et al. (1997)
(their Table 1).
