Extended Data Fig. 6: Parameters of a binary system producing a radio signal compatible with the FRBs presented here through gravitational lensing.

The system, located at 1 Gpc, contains a 1M☉ pulsar emitting 1-Jy pulses that are lensed by its companion. The allowed parameter space is shown with brighter colours as a function of the minimum alignment angle (colour-coded), companion mass and separation of the binary system.
