Combined CCFs from every UVES-sized order after the VO injection. The black line shows the CCF using the complete VO line list. The solid and dotted red lines show the CCF using the reduced line list described in Sect. 2.4 and the CCF using the non-selected transitions, respectively. The grey region depicts the excluded velocity range used to determine the noise level in the CCF. The peaks at −25 and 0 km s−1 are the injected and observed signals, respectively.
