The variable peaks on the flat–topped CIII-569.6nm line of the WC-star in the WR 79–system are interpreted as additional emissions, produced in the colliding wind region of the two stars. The minimum and maximum distances of the appertaining radial velocity curves yield the important parameter i and so the system-masses. Synthetic profiles strongly support the present model.
