IFS and IRDIS images from star-hopping RDI reductions shown with same scale and orientation (North is up, east is left). Left: S/N map of the IFS Y–H band reduced image, showing only the real planets. The azimuthal filtering creates the dark negative arcs around the planets. They are more pronounced in the IFS reduction because more images were combined than for the IRDIS reduction. Right: S/N map of the IRDIS K1 + K2 band reduced image, showing only the real planets. The star, at the center of the black circle, is masked by the coronagraph. No new planets are detected in the newly probed region around 0.1″ separation above the contrast limit of 11.2 mag.
