Constraints on companion mass and semi-major axis for planets orbiting L 363-38, based on the ESPRESSO residuals after subtracting the signal from the planet and on the contrast curve computed for the NaCo observations. The 2D histograms show the percentage of companions with mass and semi-major axis in a given bin that would be detected, if present, with the current ESPRESSO observations (upper left) and NaCo images (upper right). The percentage of companions detected in at least one of the datasets and in the HCl data only are shown in the lower left and lower right panels, respectively.
