Long description

An image is shown with scales on the axes. The horizontal axis is labelled ‘Delta R A in arcsec’ and ranges from 0.9 to negative 0.9 in decrements of 0.1 unit. The vertical axis, labelled ‘Delta Dec in arcsec’, ranges from negative 0.9 to 0.9 in increments of 0.1 unit. At the centre of the graph (0.0, 0.0), a central cavity with a star as a tiny bright dot is shown against a deep red background. A planet is shown as a bright light on the lower left of the cavity. The planet’s disc is shown as an elliptical orbit around the cavity, with an axis of 1.4 arcsec in the vertical direction and 1.0 arcsec in the horizontal direction. The disc appears as a brighter shape mostly on the right side of the star.
