Left panels: correlations between the different asymmetry parameters and their corresponding RV estimates in the case of an equatorial 1% spot on the simulated Sun. Right panels: correlations between the different width parameters and their corresponding RV estimates for the same spot. In the presence of a spot, both the shape and width of the CCF change as the star rotates. However, only the asymmetry produces a statistically significant correlation with the different RV estimates. The width parameters and their corresponding RV estimates present weak correlations and, in general, much weaker correlations compared to the results obtained when an equatorial 3% facula is present on the simulated Sun.
