Fig. 2


Top: map of the synthetic T5-type planets (T ~ 2000 K) of 1 × 10-4 after injection in H2 filter (left) and SDI reduction (right) of IRDIS data. A slight misalignment of the Lyot stop causes the oblique stripe going through the image. Bottom: simulated T5-type (T ~ 1100 K) planets at a contrast of 3 × 10-5 injected in the IFS pre-reduced datacube (left) and after the SD reduction (right). In the central part of the image, the SD cannot work properly for the reasons explained in Sect. 4. The images show the 15th channel of IFS at λ = 1.09μm.
