Description:
We present the data from an extensive, moderately deep (bJ∼19.5)
spectroscopic survey of ∼600 galaxies within four regions of the sky
located near the South Galactic Pole. About 75% of the measured
galaxies are in an approximately 3x1.5sq.deg region dominated by the
rich cluster of galaxies Klemola 44 (Abell 4038). The other three
small areas cover about 1sq.deg each. Here, we discuss in detail the
observing and data reduction strategies, and the completeness of and
errors in the measured redshifts. The data collected are being used
for: (i) a study of the large-scale redshift distribution of the
galaxies in each field, and (ii) a thorough dynamical investigation of
Klemola 44. Results from these analyses will be presented in
forthcoming papers.
