Spectrum of the (0,0,1) 14_3,12–13_4,9 transition of para H₂O in R Hya (upper panel). Following the IPL catalog, we assume a rest frequency of 236.8054 GHz (line 4 in Table 2). The line profiles are extracted from the combined high and mid resolution data cubes for circular apertures with 0.″708, 0.″12 and 0.″16 diameters. The vertical dashed line marks the water line frequency shifted by the systemic velocity of the star in Table 1). The lower panel shows the same spectrum toward S Pav.
