Combining low- and high-resolution datasets. The color-code is the same as in Fig. 14. Left column: ESPRESSO CCFs with injected models retrieved for the equilibrium temperature and 1600 lines. The best Gaussian-fit model shown in black evaluates whether or not the injected model could be retrieved in the ESPRESSOdata. Middle column: high-resolution model that is injected into the ESPRESSO data. Right column: HST data in black are compared to low-resolution models. A minimization algorithm is applied to estimate the and BIC of each model compared to the data. Rows: same model with different cuts in pressure simulating different gray cloud-deck.
