Abstract:
We present the final data from the spectroscopic survey of the
ROSAT-ESO Flux-Limited X-ray (REFLEX) catalogue of galaxy clusters.
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.
