Fig. A.1.
Example of the data-reduction procedures. These data are from Night-1 observation. (a) original spectra from the HARPS-N pipeline (Data Reduction Software). These are order-merged spectra. Here the spectra are shifted into the Earth’s rest frame. (b) spectra after normalisation and correction of blaze variations. (c) residual spectra after the removal of stellar and telluric lines using SYSREM.
