Description:
We present redshifts and blue magnitudes for a sample of 264 'field'
galaxies virtually complete to a limiting magnitude of bj~=16.80mag.
The galaxies were selected by sampling one galaxy in every three in
order of apparent magnitude on each of nine high-latitude UK Schmidt
(UKST) fields. Photometric data were provided by COSMOS machine
measures of UKST plates, zero-pointed with CCD photometry. The
spectral data came from observations with the 1.9-m telescope at the
South African Astronomical Observatory (SAAO), and the resulting
radial velocities have a precision of ~±130km/s. This survey
augments substantially the Durham/AAT redshift survey. In this paper
we discuss the observational techniques and reduction procedures.

Note (1): the symbols have the following meaning:
* Indicates galaxy with superimposed star.
? This object has a stellar spectrum but is clearly diffuse on the
plate.
Note (2): only one of the two numbers, r or Nem, is provided.
r is the ratio of the height of the true peak to the average peak
in a(x). For more details, see Tonry & Davies (1979AJ.....84.1511T 1979AJ.....84.1511T).
Note (3): the numbers mean the following:
0: emission line velocity
1, 2 and 3: cross-correlation quality ratings in section 4.2
4: no redshift could be obtained from the spectrum
5: the one object whose redshift we took from RC2 Cat. VII/112
6: galaxies which have velocities, but are not in the one-third
sampling criterion
9: two-thirds whose redshifts we did not attempt to measure
Note (4): Any alternative designation for the objects (e.g. NGC number) is
given here. Also, emission-line redshifts are given for those objects
which showed emission but whose cross-correlation velocities were
adopted for the survey.
note E: Emission line velocities for objects whose cross-correlation
velocities were deemed more reliable. The number of emission lines
on which the measure is based is given in brackets.
