H﹩{}_{2}^{16}{\rm{O}}﹩ ﹩{10}_{\mathrm{2,9}}﹩–9﹩{}_{\mathrm{3,6}}﹩ emission toward HL Tau (colors). Black contours show the 3σ, 4σ, 5σ, 6σ levels (σ = 1.2 Jy km s−1 beam−1). The beam is marked in white. Emission is integrated over –22.5 to 10 km s−1 (﹩{v}_{{\rm{source}}}﹩ = 7.0 km s−1) in the uv plane before imaging; no redshifted emission is detected. The dashed line indicates the direction of the H2 jet and the dotted line shows the direction of the disk. The data used to create this figure are available.
