Recovery of a 0.2 m/s planetary signal at different orbital periods using the CV-Temp model. Each row corresponds to an injected period of 10, 50, and 100 days, respectively. Left: Periodograms of the traditional CCF RVs (green) and the neural-network-predicted RVs (orange). Right: Periodograms of the predicted DS. The dashed line indicates the 0.1% FAP threshold, and the insets highlight the region around the injected period for the ten independent evaluation sets. The planetary signal is consistently recovered in the DS periodograms for all tested periods, while remaining undetected in the RV-based analyses.
