Propagation of RM+CLV model impact for each exposure from Fig. 4 in the final transmission spectrum. The wavelength position of the sodium doublet is indicated as a dotted grey vertical line; the centre of the high-velocity absorption components are indicated as dashed grey vertical lines. The main impact of the RM+CLV correction is at the centre of the sodium doublet, only impacting the mid-centre data and on the blue side of the high-velocity absorption components.
