Left: significance map. Right: degeneracy plot. Simulated data of a companion located at a separation of 30 mas, a position angle of 90°, and contributes 10% of the total flux (white triangle). The white circle shows our best fit position. We see the distinctive lobing of a partially resolved companion. In this case with excellent S/N we are able to accurately identify the location of the companion but in practice this is not always the case.
