HIFI spectra of the H₂¹⁷O/H₂¹⁸O (left) and H₂¹⁶O (right) lines (in black), with continuum for G327.3–0.6 hot core pointed position. The best-fit model with varying (from line to line) and constant (2.6 km s^-1) turbulent velocity is shown as a red and dashed blue line above the spectra. Vertical dotted lines indicate the V_LSR (–43.2 km s^-1 from the line modeling). The spectra have been smoothed to 0.2 km s^-1, and the continuum is divided by a factor of two.
