EMC distributions around the Ca II IRT lines at 8500 Å and 8664 Å, and the He I lines, for both nights combined. The distributions are obtained using 20 000 iterations and a 2Å bandwidth for the Ca II IRT lines and 5Å bandwidth for the He I, to cover the overall absorption feature observed in the transmission spectrum. The results of the ‘in-in’ sample are shown in red, the ‘out-out’ in green, and the ‘in-out’ in blue. The dashed lines show the best-fit Gaussian profiles of the distributions.
