RVSearch summary plot for YBP 2018. Panel a shows the RV time-series with the best-fit model with the residuals shown in panel b. Datapoints labelled HRS are from the old high-resolution spectrograph installed at the HET. All of the RV observations are corrected to the zero point of HARPS and are therefore treated as coming from one instrument. Panel c shows the phase-folded RV curve with the values derived from the MCMC. Panels d and f show the periodogram of the one- and two-planet models and panel e plots the significance of the RV signal as a function of the number of observations.
