Periodogram analysis of 70 Oph B PFS RV residuals after subtracting the binary acceleration. Top: Agatha BFP where the dashed–dotted line marks ﹩\mathrm{ln}\,{\rm{BF}}=5﹩. Bottom: MLP where the dashed–dotted line marks ﹩{\rm{\Delta }}\mathrm{ln}{ \mathcal L }=10﹩. Neither method detects a significant periodic signal in the RV data of 70 Oph B.
