Left panels: RM plus CLV model (top) and the RM alone model (bottom) for Fe I. Middle panels: cross-correlation residual maps of Fe I for the combination of two HARPS-N nights after removing the modelled effects in the left panels. The red horizontal lines represent the beginning and end of the transit. The light-blue tilted dashed line shows the position of the expected signal of the planet. Right panels: cross-correlation sum plots at the expected K_p value, before (gray dotted line) and after (black line) removing the effects. In purple we show the calculated models for each effect.
