Toppanels: RVs (black dots) for HD 192310 estimated using a SN and a Normal fit. Bottom panels: residuals from the model fit using Eq. (5) (New corr. std–black dots) and the residuals from the usual correction (Usual corr. std–blue triangles), based on RV_activity = β₀ + β₁γ + β₂SN FWHM for the SN fitand on RV_activity = β₀ + β₁BIS SPAN + β₂FWHM for the Normal fit. The residuals for both the proposed correction from stellar activity are comparable.
