Results for the AU Mic observations. Top panel: RVs from AU Mic as observed (black) and as modelled by the trained NN using BIS, and FWHM indices with their respective RREs. Bottom panel: periodogram of the observed RVs (black), the NN output (red), and the difference (green). Dashed black lines indicate the rotation period and its second harmonic, and dashed blue lines indicate the orbits of the two planetary companions of AU Mic. We reach RREs as low as 10%.
