Water line profiles extracted from the extended configuration of the main array for an aperture diameter of 0.′′08 in R Hya. First two rows: six transitions of ortho H₂O as defined in Table 2: lines 1, 6, 8 (including line 7 separated by 12.7 MHz, or 15.0 km s⁻¹, from line 8) and lines 13 and 14. Last row: two transitions of para H₂O as defined in Table 2: lines 10 and 12. The spectra are converted from the observed frequency to the LSR frame using the H₂O catalog Une rest frequencies given in Table 2. In all spectra, the blue vertical line indicates the adopted new LSR systemic velocity as shown in Table1. For line 1 (upper left panel), file red verticad line shows the LSR velocity for the slightly different frequency determined in this work. Spectral resolution varies from ~1.1 km s⁻¹ (268 GHz) to ~1.3 (222 GHz) km s⁻¹.
