Central part of images without detection noise produced by the simulation, after the coronagraph (left) and after the speckle calibration by the self-coherent camera (middle and right). The image size is  ~64  ×  64 (λ/D)² (λ = 0.675 μm). In the two left images, there are two jovian planets of contrasts  ~10^-8 and  ~10^-9 (red circles). In the right image, we indicate the calculation area of the profiles shown in Sect. 3 with a white dotted line. The intensity scales are linear and identical.
