RVs reduced by SERVAL prior to (blue) and after (orange) the HARPS fiber change in 2015 plotted against time. The error bars are smaller than the size of the markers. A sinusoidal fit is plotted in black and reveals the RVs to be consistent with a long-lived, coherent signal that could (when examined in isolation to other diagnostics) be attributed to a brown dwarf orbiting the primary.
