Stellar surface intensity map at 1083.31 nm computed with PYSME in the case of HAT-P-11 b. The intensity map is relative to the integrated intensity over the stellar map at 1083.31 nm. The grid contains 101 × 101 cells, and the planet’s trajectory is shown with a red solid line with black dots indicating the planet’s center at each observed phase. The planet solid disk is shown at a given phase, with the underlying stellar cells being excluded from the master spectrum computation.
