Ghost, thorium-argon, and continuum corrections performed by YARARA on HD 10700. The river diagram is produced in the BERV rest frame. Top: spectral time series before YARARA corrections. Spectra suffer from thorium-argon contamination (bright vertical lines, for example close to 3840 Å) and Fabry-Pérot contamination by a ghost of the simultaneous calibration fibre (vertical bright comb around 3822 and 3851 Å). The strong contamination around 3819 and 3849 Å is due to two ghosts of the science fibre. Middle: model of the contamination fitted by YARARA. Bottom: residual river diagram after YARARA correction.
