Extended Data Fig. 4: Channel maps of the H218O emission.
From: Pristine ices in a planet-forming disk revealed by heavy water
The pink contour indicates the region where H218O 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 H218O are expected to emit.
