Spectra of R Hya, S Pav and R Aql in the J = 27/2 and 29/2 rotational levels of OH extracted from the high resolution data cubes for an aperture diameter of 0/08. The three left and three right panels correspond to J = 27/2 and 29/2, respectively. In each spectrum, the two nearby emission features correspond to the two hyperfine transitions of each A-doublet (dotted blue and red vertical lines). Note weak absorption features observed in all six spectra. In the J = 29/2 spectra, the most negative velocity emission feature (closest to the F′ – F″ = 15–15 transition) is the 252.172 GHz line of water. The spectra are converted from the observed frequency to the LSR frame using the OH catalog line rest frequencies given in Table 3. Line 2 at 221353.48 MHz and line 8 at 252145.35 MHz are taken as the reference frequencies for each spectrum in the J = 27/2 and 29/2 states; they are placed at the adopted new systemic velocities (see Table 1).
