High resolution channel map of S Pav and IRC+10011 in the (0,1,0) 7_7,1–8_6,2 rotational transition of water (line 12) at 262.898 GHz (upper and lower panels). Caption as in Fig. 6 except for the line frequency, velocity range and the line peak flux density, 12.8 mJy/beam (S Pav) and 31.5 mJy/beam (IRC+10011); the typical r.m.s. is 1 and 2 mJybeam⁻¹, respectively. The line HPBW is (24×18) mas at PA −20° (S Pav) and (26×20) mas at PA 22° (IRC+10011). The continuum HPBW is (25×20) mas at PA −13° ( S Pav) and (27×19) mas at PA 31° (IRC+10011).
