ALMA Band 5 images of the HL Tau disk and the 321 GHz H₂O line. Top left: continuum. Right panels: JvM-corrected integrated intensity maps of the H₂O line at 183 GHz imaged with r = 0.0 (top) and r = 2.0 (bottom). These maps provide high and moderate spatial resolution. Top-right inset: zoomed-in view of the inner 0^′′.2. This highlights the approximate water snow line location derived by Guerra-Alvarado et al. (2024) Bottom left: reimaged H₂O 321 GHz line originally presented in Facchini et al. (2024). The beams are indicated in the bottom-left corners of the respective panels. The dust rings and gaps derived from high-resolution ALMA observations are indicated with solid and dashed arcs in each panel (ALMA Partnership 2015; Carrasco-González et al. 2019; Guerra-Alvarado et al. 2024), and a 20 au scale bar is shown in the bottom-right corner of the bottom-right panel.
