Abstract:
In the third of a series of papers on large-scale structures behind
the southern Milky Way, we report here on redshifts obtained at the
South African Astronomical Observatory (SAAO) in the Great Attractor
region (318°≲l≲340°, |b|≤10°, Woudt, 1998, Ph. D.
Thesis, University of Cape Town). This region encompasses the peak in
the reconstructed mass density field, associated with the Great
Attractor (Kolatt et al., 1995MNRAS.275..797K 1995MNRAS.275..797K, Dekel et al.,
1999ApJ...522....1D 1999ApJ...522....1D) and covers the crossing of the Supergalactic
Plane with the Galactic Plane. Our deep optical galaxy search in the
Zone of Avoidance (ZOA) in this region (Woudt, 1998, Ph. D. Thesis,
University of Cape Town) has resulted in the detection of 4423
galaxies with observed diameters larger than 0.2arcmin. We have
obtained reliable redshifts for 309 galaxies of the 4423 galaxies with
the ``Unit'' spectrograph (first with a Reticon, then with a CCD
detector) at the 1.9-m telescope of the SAAO. An additional 13
tentative redshifts are presented.

Note (3): *: Redshifts are also available in the literature
1: WKK 4001: The redshift measured at the SAAO for this galaxy
(v=5937±250km/s) is in disagreement with the value quoted in
the literature (v=4700±100km/s, Fairall, 1981MNRAS.196..417F 1981MNRAS.196..417F)
2: WKK 5792: The redshift measured at the SAAO for this galaxy
(v=13487±101km/s) is in disagreement with the value quoted in
the literature (v=3500±70km/s, di Nella et al., 1997,
Cat. J/MNRAS/287/472). There is a positional mismatch of 1.1
arcminutes between WKK 5792 and the galaxy quoted by di Nella
et al. (1997, Cat. J/MNRAS/287/472). However, after visual
re-examination, no galaxy is seen on the IIIaJ Sky Survey at the
position of di Nella's galaxy and we believe that this velocity
should not be trusted.
3: WKK 6180/6212: The redshifts measured for WKK 6180 and WKK 6212
(v=4619±127km/s and 3196±95km/s, respectively) are in
disagreement with the value quoted in the literature
(v=3100km/s and v=4911km/s, respectively, West et al.,
1981A&AS...46...57W 1981A&AS...46...57W). This might be due to an identification error
4: WKK 7055: The spectrum is contaminated by the light of a Galactic
foreground star. However, a reliable redshift could be obtained.
GR6: These galaxies have been observed at higher spectral resolution
with grating 6 (100Å/mm), see also Sect.∼2.1.
Sy1: This galaxy, WKK 6092, has been classified as Seyfert 1 (Woudt
et al., 1998A&A...338....8W 1998A&A...338....8W)
