Cross-correlation results in the K_p – V_sys space for the species detected in WASP-189 b’s atmosphere during eight transit events with HARPS, HARPS-N, ESPRESSO, and MAROON-X combined. Each panel shows the significance of the detection for a given species, and the solid lines indicate the expected location of the signal if we assume a symmetric planet with a static atmosphere. Deviations from this location can be indicative of chemical asymmetries and dynamical effects. The lower-right panel shows the cross-correlation result in K_p – V_sys space for a template containing all species at a temperature of 3000 K. As previously seen in Prinoth et al. (2022), the atmospheric signal is located at a systemic and projected orbital velocity smaller than the true values, indicating a global dayside-to-nightside flow.
