Same as Fig. 2 for the zoomed () channel maps of post-imaging continuum-subtracted H₂O v₂ = 1J_Ka,Kc = 5_5,0−6_4,3. The white contours represent 6, 12, 18, 30, and 42σ and yellow contours represent −24, −18, −12, and −6σ, where σ = 0.85 mJy beam^-1 is the map rms noise. The circular restoring beam of FWHM for the H₂O images is indicated in white in the bottom left corner of each panel.
