Extended Data Fig. 3: Channel maps of the HDO emission.
From: Pristine ices in a planet-forming disk revealed by heavy water
The pink contour indicates the region where HDO is expected to emit if the emission is Keplerian and the white contours indicate the 3 and 4σ level in these channels. The cyan and red contours indicate the Keplerian mask where the neighboring lines that are blended with HDO are expected to emit.
