Influence of Stellar Activity on Radial Velocity. (Top) Values of the $log{R}_{\text{HK}}^{\prime }$ activity index throughout the night. This index is derived from the calcium H and K lines and is indicative of chromospheric activity. The low scatter indicates that stellar activity does not significantly influence the obtained RV dataset. (Bottom) RV residuals after subtracting our R-M effect model from the observed data (blue) and RV residuals after subtracting the R-M effect model with a linear ephemeris (red; Luque et al. 2023). The blue model is preferred due to the lower standard deviation.
