Different steps used by team 7 to detect the 3.77-day planetary signal present in system 2. Upper left panel: DFT of the RVs, FWHM, BIS SPAN and ). Upper right panel: cleaned DFT (CDFT) obtained after applying the CLEAN algorithm to the DFTs of all observables. In the inset, the resulting pass-planet filter in the frequency domain, that is later applied to the DFT of the RVs to mitigate the effect of stellar signals. Lower left panel: RVs before (black circles) and after (red squares) applying the pass-planet filter. Lower right panel: phase-folded result of the Keplerian fit to the 3.77-day planetary signal found in the RVs.
