Distributions of the EMC analysis for the 12 Å passband. The resultsfor the transmission spectrum method are shown. As expected the “in–in” (red) and “out–out” (blue) distributions are centred around zero (no planetary detection) and the randomised “in–out” distribution shows a detection (black). On each night a different number of spectra was taken, which means that each randomisation will give a different number of counts, which results in a different scaling on the y-axis. This has no influence on the overall result.
