Table 1: Fit parameters for a $\beta$ model centred on M1 and M2: S₀ is the central surface brightness, $r_{\rm c}$ is the core radius, and $\beta$ is the slope parameter.
Table 2: List of point sources detected in the field covered by MOS CCD $\char93 1$ . Columns 1-3 give the source identification number, and its coordinates (J2000). In Cols. 4 and 5 the source count rate (in counts per second) and the radius (in arcseconds) out to which the source can be detected, respectively, are listed.
Table 3: Results of the spectral fits for the whole cluster. Column 1: line number. Column 2: detectors in use. In Cols. 3-6 the fit parameters (temperature in keV, metallicity in solar units, redshift and HI column density in $10^{20}\ {\rm cm}^{-2}$ ) are listed. In Col. 7 is the fit reduced $\chi ^2$ .
Table 4: Results of the spectral fits for the three subregions using a MeKaL model. HI column density and redshift are fixed to the average values for the whole cluster. Column 1: region analyzed. In Cols. 2 and 3 the fit parameters (temperature in keV and metal abundance, respectively) are listed. In Col. 4 is the reduced $\chi ^2$ of the fit.
Table 5: Numerical values for the mass determination in the two subclusters M1 and M2.
Table 6: Numerical values for the mass determination in cluster CL 0939+4713 for two specific radii; the masses are computed using the fit parameters for the profile centred on subcluster M2.
