The REFLEX survey covers 4.24 steradians (34% of the entire sky) below a declination +2.50° and at high galactic latitude (|b|<20°). The full survey includes 447 galaxy clusters with a median redshift of 0.08 and is better than 90% complete to a limiting flux of fX=3x10-12ergs/s/cm2 (3fW/m2, 0.1 to 2.4keV), representing the largest statistically homogeneous sample of clusters to date drawn from the ROSAT All-Sky Survey (RASS). Here we describe the details of the spectroscopic observations carried out at the ESO 1.5m, 2.2m and 3.6m telescopes, the data reduction and redshift measurements techniques. The spectra typically cover the wavelength range 3600-7500Å at a two-pixel resolution of ∼14Å . From calibrations and external checks the redshifts are accurate to a typical rms error of ±100km/s.

Note (1): to distinguish among stars, galaxies and clear AGN-like spectra. Note (2): giving the ratio between the height of the cross-correlation peak and the overall rms noise of the same function.
