MLPs of the combined and individual 70 Oph A RV residuals after removing the acceleration of 70 Oph B. Per-instrument offsets and jitter are simultaneously fit at each trial frequency. The red dashed line marks the 1% FAP threshold (﹩{\rm{\Delta }}\mathrm{ln}{ \mathcal L }=10﹩). Dominant spectral window peaks are noted above each panel. Gray dotted lines mark signals of interest at 9.7, 11.9, 20.3, and 59.2 days.
