Azimuthally averaged radial profiles of the H₂O line at 183 GHz imaged with a robust parameter of 0 (blue), 0.5 (orange), 1 (green), 1.5 (purple), and 2.0 (pink), all corrected for the non-Gaussian beam shape, and the continuum emission (black). The continuum emission is presented in arbitrary units. The upper limit on the water snow line location is indicated with the vertical red line. The beams are indicated with the horizontal bars in the top-right corner.
