Fig. A.1

Molecular mapping detection of CO for real PZ Tel B data using cross-correlation for spectroscopy. This figure is an analogue to Fig. 1, applied to the CO molecule instead of H₂O. It is even more obvious in the case of CO, that the cross-correlation and molecular maps fail to yield a clear peak under worse conditions.
