Table 1: 44 Bootis observation log during revolution 274.
Table 2: X-ray luminosities of 44 Boo in the 0.3-2 keV and 2-5 keV energy bands averaged over the different observations periods and corrected for interstellar absorption. The percentage contribution in flux of hot plasmas ( $kT \ge$ 1 keV) is indicated between bracketts.
Table 3: Best fit parameters to EPIC data using a 3 components MEKAL model (Mewe et al. 1985). The spectral fitting was conducted in the 0.3-5 keV band with the same abundance relative to the Sun for all components.
Table 4: Best fit parameters to EPIC data using a plasma emission model built from the MEKAL code in which the emission measure distribution follows a power-law in temperature of the forme $EM_{\rm max} \times (T/T_{\rm max})^{\alpha }$ .
Table 5: Positions, transition, temperatures of maximum line formation and fluxes of the strongest lines in RGS spectra.
