Scientific paper

We analyzed the intensity distribution of the 3/4 keV and 1/4 keV diffuse soft X-ray background by correlating the \rosat all-sky survey with the Leiden/Dwingeloo \hi survey. We found that the 3/4 keV and 1/4 keV intensity distributions can be modelled by a contribution from an isothermal (kT=3D0.135keV) flattened X-ray halo superposed on the radiation from an extragalactic X-ray background. The exponential scale height of the X-ray halo is about 4.4kpc and its radial scale length is about 15kpc; the X-ray halo luminosity, L_X, is about 7* 10(39) erg s(-1) .
