Time series comparing cycle 23 model and cycle 24 observations. The orange lines represent smooth time series from a running average (over 28 d). The upper panel shows the model RV from Meunier et al. (2010a) in red and the HARPS-N observed RV in green. The middle panel shows the Sac Peak S-index (black) and the HARPS-N S-index (green). The last panel shows the Sunspot number from SILSO/SIDC (https://www.sidc.be/silso/) over cycles 23 and 24.
