Optical depths for γ-rays in the radiation field of the Eta Carinae star (left panel) and its companion star (middle panel) as a function of energy of injected γ-ray photons. Specific curves show the results for the propagation angle of the γ-ray photon (measured from the direction defined by the injection place and the center of specific star) equal to: α = 0^o (dot-dot-dashed curve, direction outwards of the specific star), 30^o (dot-dashed), 60^o (dotted), 90^o (dashed), 120^o (solid). γ-rays are injected at the distance of 1.4R_EC from the surface of Eta Carinae and at the distance of 6R_comp from the surface of the companion star. The dependence of the optical depths on the distance from the Eta Carinae star is shown in the right panel for the injection angle of α = 60^o and the distances 1.4R_EC (dotted), 2R_EC (solid), 3R_EC (dashed), 5R_EC (dot-dashed), and 10R_EC (dot-dot-dashed), respectively.
