Shape of the measured planet signal from the first night of observations (black line) compared to the theoretical analogue (cyan line) computed by convolving the autocorrelation function of the bestfitting model, a Gaussian instrumental profile with FWHM = 6.0 km s⁻¹, and a rotational profile (rigid-body rotation, from Brogi et al. 2016) with equatorial velocity of 3.4 km s⁻¹ and day-to-night wind speed of −1.6 km s⁻¹. The agreement between the two profiles is remarkable.
