Cartoon visualising the expected emission regions, based on the derived excitation temperatures, emitting radii, and optical depths, of the multiple components of H₂O. Shown are also the expected emission locations of CO, CO₂, HCN, and C₂H₂ adopted from Temmink et al. (2024). The CO is decomposed in two components: one broad component (BC) tracing the Keplerian rotation of the disk, and a narrow component (NC) tracing a disk wind.
