Number of photons between 100 and 230 Å (in units of that from a 125 000 K blackbody) as a function of the distance from the WR star surface (the intermediate model of Table A.1 (f_vol = 0.3, Φ = 0) along the line joining the stars). The compact star is located at 2.4 R_WR. The solid line shows the contribution from the WR star and the dashed line that from the compact star (X-ray source). The dotted line shows the coadded contribution.
