Our technique correctly accounts for past light-cone effects on the observed clustering and follows the non-linear evolution inredshift of the underlying dark matter correlation function and cluster biasfactor. The conversion of the limiting flux of a survey into the correspondingminimum mass of the hosting dark matter haloes is obtained by using theoret-ical and empirical relations between mass, temperature and X-ray luminosityof galaxy clusters. Finally, our model is calibrated to reproduce the observedcluster counts adopting a temperature-luminosity relation moderately evolvingwith redshift. We apply our technique to three existing catalogues: the ROSATBrightest Cluster sample (BCS); the X-ray brightest Abell-type cluster sample(XBACs); the ROSAT-ESO Flux Limited X-ray sample (REFLEX). Moreover,we consider an example of possible future space missions with fainter limitingflux. In general, we find that the amplitude of the spatial correlation functionis a decreasing function of the limiting flux and that the Einstein-de Sittermodels always give smaller correlation amplitudes than open or flat modelswith low matter density parameter ?0m. In the case of the XBACs catalogue,the comparison with previous estimates of the observational spatial correla-tion shows that only the predictions of models with ?0m = 0.3 are in goodagreement with the data, while the Einstein-de Sitter models have too low acorrelation strength. Finally, we use our technique to discuss the best strategyfor future surveys. Our results show that to study the clustering propertiesof X-ray selected clusters the choice of a wide area catalogue, even with abrighter limiting flux, is preferable to a deeper, but with smaller area, survey.Key words: cosmology: theory – galaxies: clusters – large–scale structure ofUniverse – X-rays: galaxies – dark matter1INTRODUCTIONExtending the study of the matter distribution to the largest scales reachable by observations can provide importantconstraints on models for the formation of cosmic structures. In fact, on very large scales the present-day fluctuationfield is just a linear amplification of the primordial one. In the past years, surveys of galaxies have been used todescribe the spatial distribution of the cosmic structures up to few hundred Mpc. It is now well established that anaccurate and efficient alternative way to describe the very large scale structure of the universe is to use the spatialdistribution of clusters of galaxies. In the framework of the gravitational instability picture galaxy clusters are themost extended gravitationally bound systems in the universe. Moreover, their typical separation is much larger thantheir expected displacements from the primordial positions. Therefore, their study can be quite useful in puttingconstraints on the cosmological parameters. This possibility is made easier by the fact that the cluster clusteringc 0000 RAS
