Warped HR 3549 image. This figure shows the bottom half of the data shown in Fig. 1, corresponding to the side where lies the companion, warped so as to align the dispersed speckles of the stellar leakages. The warping is defined by the coordinates ρ and λ of the pixels given by the “complex” calibration model of the spectral and angular dispersion laws described in Appendix A. The companion signal can be seen as a faint curved track indicated by the blue arrows.
