Enlarged view of the inner 3′′× 3′′ region of the flux-calibrated Antares image, together with the PSF references ε Sco and Aldebaran. North is up, and east to the left. a) Flux-calibrated image of Antares. The colors are shown on a logarithmic scale, but the colors in the central region are saturated. b) Image of the PSF reference ε Sco. The intensity is normalized with the peak intensity. The colors are shown on a logarithmic scale. c) Image of the PSF reference Aldebaran, shown in the same manner as in b). d) Difference between the images of ε Sco and Aldebaran. The colors are shown on a linear scale, ranging from − 5% to 5% of the peak intensity of the PSF reference images.
