Morphological corrections performed by YARARA on HARPS observations of HD 10700 for the 3849 Å line contaminated by a ghost of the science fibre. The time dimension was phase-folded at one sidereal year. Top left: L+R area deviation with respect to the Doppler shift calibration curve (see main text for the precise definition), which is therefore similar to its EW. Top middle: L−R area deviation with respect to the Doppler shift calibration curve. Top right: line depth of the line computed by a parabola fitting on the line core. Bottom left: LBL RV of the line before any correction. Bottom middle: LBL RV after YARARA flux corrections. The stellar lines present in the ghost are still visible. Bottom right: LBL RV after multi-linear de-correlation with the three morphological proxies. The 8.1 m s⁻¹ rms of the RV residuals is compatible with the median of the RV uncertainties.
