Same as Fig. 2 for the zoomed () channel maps of post-imaging continuum-subtracted H2O v2 = 1JKa,Kc = 55,0−64,3. 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.
