Exoplanet detection limits on HD 10700 HARPS spectra. We derived the detection limit maps by injecting simulated planetary signals covering periods ranging from 10 to 350 days and semi amplitude ranging from 0.3 to 1.1 m s⁻¹, into the spectra. Left: detection limit map in the period-amplitude domain. The red dots indicate the successful detection by the trained neural network of a signal with a FAP >0.1%. Middle: amplitude comparison between the injected and recovered signals in the period-amplitude domain. The amplitude difference for most of the detected signals is <20%. Right: phase difference between the injected and recovered signals in the period-amplitude domain. The phase difference for most of the detected signals is <0.04.
