Description:
Spectroscopic observations have been carried out for galaxies in the Milky
Way with the 1.9m telescope of the South African Astronomical Observatory
(SAAO). The galaxies were selected from a deep optical galaxy search
covering 266deg<~l<~296deg, |b|<~10deg (Kraan-Korteweg 1994). This is in the
extension of the Hydra and Antlia clusters and in the approximate direction
of the dipole anisotropy in the Cosmic Microwave Background radiation.

Note (1): Codes for identified emission line:
1: [OII] 3727A
2: H{gamma} 4340A
3: H{beta} 4861A
4: [OIII] 4959A
5: [OIII] 5007A
6: H{alpha} 6563A
7: [NII] 6584A
Note (2): Codes for additional remarks:
1: The spectrum of KK527 shows this to be a Seyfert 1 galaxy.
2: The spectrum of KK1963=L92-10 was measured at different sites
and - based on the emission lines [OII], H(beta),[OIII], H(alpha),
[NII] - the following velocities were obtained:
V(hel)=134, 26, 87, 10, 35, 6, 100 +/- 58 km/s. The velocity
given in Table1 is the mean of all these velocities. Further
details are given below.
3: Due to superposition of a star on the galaxy KK2508=L62-10 the
exposures were centred slightly west of the centre of the object.
For some of the galaxies other redshift measurements are available
as well (cf. section 2.2.2):
A: V(hel)= 2916+/-45km/s by Strauss et al. 1992, for KK1517=L126-24.
B: V(hel) = 1830km/s by Acker et al. 1991 for KK1853
(cf. special cases).
C: V(hel)= 5523km/s by Dressler 1991 for KK2992=L170-3.
