Abstract:
    The Southern Abell Redshift Survey (SARS) contains 39 clusters of
    galaxies with redshifts in the range 0.0<z<0.31 and a median redshift
    depth of z{bar}=0.0845. SARS covers the region 0deg<delta←65deg,
    alpha<5h, alpha>21h (while avoiding the LMC and SMC), with
    |b|>40°. Cluster locations were chosen from the Abell and
    Abell-Corwin-Olowin catalogs, while galaxy positions were selected
    from the Automatic Plate Measuring Facility galaxy catalog with
    extinction-corrected magnitudes in the range 15≤bJ<19. SARS used the
    Las Campanas 2.5m du Pont telescope, observing either 65 or 128
    objects concurrently over a 1.5deg2 field. New redshifts for 3440
    galaxies are reported in the fields of these 39 clusters of galaxies.

Description:
    Spectroscopic observations were carried out with the 2.5m du Pont
    Telescope of LCO, Chile.

Note (1): -99 = only one or two strong emission or absorption lines were found
          and no estimate of the error can be given.
Note (2): Tonry and Davis (1979AJ.....84.1511T) reliability R-value:
          a value less than 4 indicates a need to look at the spectra
          and try line-by-line Gaussian fitting
Note (3): When column Rfloat is empty, the number of individual emission or
          absorption lines used in the velocity estimation is indicated.
