Left panels: cross-correlation residual maps of Fe I, Fe II, Ca II, TiO, VO, V I, Mg I, and Na I for combination of two night from HARPS-N. Red horizontal map shows beginning and end of the transit. Light-blue tilted line presents trace of expected signal from the planet. Middle panels: significance map for Kp in a range of 0–300 km s⁻¹, we expect signal from the planet in the 0 km s⁻¹ radial velocities and K_p = 185.3 km s⁻¹ marked with dashed lines. Right panels: S/N plot for expected Kp value. Here, the RM+CLV effects have not been corrected.
