Extended Data Fig. 8: Modelling orbital variations of the PD and PA.
From: Cygnus X-3 revealed as a Galactic ultraluminous X-ray source by IXPE

(A) Geometry of the reflector. (B) Dependence of the PD and PA in the 3.5–6 keV band on orbital phase for the Main observation is shown with blue crosses. The red curve is the model of the reflection from a bow shock.
