Correlation curves and χ²-maps of synthetic data of HD 179949. A synthetic planetary signal was injected in the spectra with parameters: sini = 0.77 and F_p/F_s = 0.003. Left: using our observing strategy. Right: random distributed observing dates. The routine successfully recovers the signal at sini = 0.78 and F_p/F_s = 2.8    ×    10^-3 in both cases, although, when using our strategy, the correlation degree is stronger, and the parameters are better determined compared with the right panel.
