Illustration of the projected orbit of the binary system considering γ-ray emission towards the line of sight and its possible attenuation by γ-ray absorption as described in the text. Scenario 1 (left): external black-body absorber (e.g., hot gas surrounding the binary system). Scenario 2 (right): internal absorber (e.g., hot shocked gas in the wind collision region).
