Fig. 6
Cross-correlation function map for DI Psc. The image is the average of three correlation maps obtained from cross-correlating our individual Doppler reconstructions (Ca i 6439, Fe i 6430, Fe i 6421), excluding the lithium inversions. The dots with the error bars represents the correlation peaks fitted with Gaussians per latitude bin of 5°. The best fit suggests an antisolar differential rotation of α = −0.083 ± 0.021.
