Simulation results when telluric residuals were injected at a 3 ± 1% level. Top: resulting RV time series from the simulations in time (left) and BERV (right) spaces. Bottom: their respective GLS periodograms. The RVs computed with a wide and narrow BERV coverage are indicated in red and green, respectively. The significance levels of FAP = 10⁻³ and FAP = 10⁻⁵ are indicated by the solid and dashed horizontal lines, respectively. The gray line in the periodogram corresponds to the window function.
