Abstract:
We present the catalogue of the REFLEX Cluster Survey
providing information on the X-ray properties, redshifts, and some
identification details of the clusters in the REFLEX sample. The
catalogue describes a statistically complete X-ray flux-limited sample
of 447 galaxy clusters above an X-ray flux of $3 10^{-12}$ erg s$^{-1}$
cm$^{-2}$ (0.1 to 2.4 keV) in an area of 4.24 ster in the southern sky.
The cluster candidates were first selected by their X-ray emission in the 
ROSAT-All Sky Survey and subsequently spectroscopically identified in 
the frame of an ESO key programme. Previously described tests have shown 
that the sample is more than 90% complete and there is a conservative upper 
limit of 9% on the fraction of clusters with a dominant X-ray contamination 
from AGN. In addition to the cluster catalogue we also describe the complete 
selection criteria as a function of the sky position and the conversion 
functions used to analyse the X-ray data. These are essential for the precise
statistical analysis of the large-scale cluster distribution. This data set 
is at present the largest, statistically complete X-ray galaxy cluster sample.
Together with these data set we also provide for the first time the full 
three-dimensional selection function. The sample forms the basis of several 
cosmological studies, one of the most important applications being the 
assessment of the statistics of the large-scale structure of the universe and 
the test of cosmological models. Part of these cosmological results have 
already been published.

Description:

The following tables provide the catalogue as well as several data files 
necessary to reproduce the sample preparation. These files are also required 
for the cosmological modeling of these observations in e.g. the study of the 
statistics of the large-scale structure of the matter distribution in the 
Universe and related cosmological tests.

The contents of the 9 tables described in more detail in the following is
(where the numbering is the same as in the paper):

Table 2: Count rate to flux conversion factors for different
       temperatures (for $Z = 0.3$ solar, $z = 0$) as a function of column 
       density. The values quoted give the 0.1 - 2.4 keV flux per counts in the 
       0.5 to 2 keV band (channel 52 to 201) in units of $10^{-11}$ erg  
       cm$^{-2}$ counts$^{-1}$. The last column gives the hardness ratio for an 
       assumed temperature of 5 keV, defined as  (counts(0.5 - 2.0keV)
       -counts(0.1-0.4 keV))/(counts(0.5-2keV)+counts(0.1-0.4 keV)).
Table 3: K-correction table for different temperatures and redshifts. The 
       given value is to be multiplied with the luminosity in the observed band 
       to obtain the luminosity in the rest frame band.

Table 4: Conversion factor to be multiplied to the flux in the 0.5 to 2.0 keV
       band to obtain the flux in the 0.1 to 2.4 keV band as a function of 
       temperature.
Table 5: Conversion factor of the flux/luminosity in the 0.1 to 2.4 keV
       band to bolometric flux/luminosity as a function of temperature
Table 6a: The REFLEX cluster catalogue (for a Lambda-cosmological model with 
       Omega_m = 0.3, Omega_l = 0.7 and h = 0.7)
Table 6b: The REFLEX cluster catalogue (for an Einstein-de Sitter model 
       with Omega_m = 1.0, Omega_l = 0.0 and h = 0.5)
Table 7: X-ray properties of the REFLEX galaxy clusters  (for a 
       Lambda-cosmological model with Omega_m = 0.3, Omega_l = 0.7 and h = 0.7)
Table 8: Statistics of the sky coverage as a function of the sensitivity.
Table 9: Sensitivity as a function of the sky position in the REFLEX survey 
       region. Also given are the RASS 2 exposure distribution and the 
       line-of-sight galactic hydrogen column density
