High resolution channel maps of high energy (8331 K) (0,3,0) 8_3,6–7_4,3 transition of H₂O at 222.014 GHz in R Hya and S Pav (upper and lower panels). Caption as in Fig. 6 except for the velocity range and the line peak flux density, 9.3 and 6.5 mJy/beam in R Hya and S Pav, respectively; the typical r.m.s. noise is ~1 mJy/beam in both stars. The LSR velocity in each panel is determined from our own rest frequency, 222017.31 MHz, whose uncertainty is low compared to that in W2020 (see Table 2). The HPBW is (41×30) mas at PA = 45° and (34×25) mas at PA = 67° for the line and continuum in R Hya, respectively, and (27×21) mas at PA −3° (line) and (25×20) mas at PA −13° (continuum) in S Pav.
