Spectral energy distributions for the radiators of the intermediate spectral state at Φ = 0 (along the line joining the centers of components). Solid lines show the WR spectra at the photosphere (125 000 K blackbody) and the absorbed spectra at distance 2 R_WR from the WR surface. The dashed lines show the compact star spectra (unabsorbed and absorbed at distance 0.1 R_WR from the WR surface). The dotted lines show some partially cut blackbodies used to compute force multiplier grids.
