Fig. C.1

Candidates for stars with images in two epochs: HD 22049, HD 26913, and HD 41593. The images display the central star under the coronagraph. Faint companion candidates in the field of view are indicated by circles and are enumerated (cf. Table D.1). The scale is indicated in the image. North is at the top and East is to the left. The PSF of the central star has been removed in a rectangular area centred on the star and a smoothed image has been subtracted. The residual speckle pattern and the diffraction spikes of the mount of the secondary mirror remain visible (several of those due to the addition of several exposures). In addition, there are reflections, ghosts, a vignetted region to the lower left, and the shadows of the other three coronagraphs.
