and +4 [kms$^{-1}$]{} are IS. $V_{\rm opt}$ is unknown.

068.3$-$02.7 (He 2-459) Roughly parabolic profile with IS dips just outside the red wing. The very uncertain $V_{\rm opt}$ ($-72.0\pm20.0$ [kms$^{-1}$]{}) differs from $V_{\rm o}$ by $\sim
33$ [kms$^{-1}$]{}. CO(1–0) features at $-$9 and $-$15 [kms$^{-1}$]{} (+9 and +3 [kms$^{-1}$]{} LSR) reported by Zhang et al. (2000) are likely interstellar.

069.6$-$03.9 (K 3-58) Strong, double-peaked profile. $V_{\rm opt}$ is unknown.

074.5+02.1 (NGC 6881) Probably double peaked profile, but strong IS contamination (spikes) on blue side. $V_{\rm o}$ consistent with $V_{\rm opt}$ ($-14.4\pm2.3$ [kms$^{-1}$]{}).

079.6+05.8 (M 4-17) Flat-topped or concave profile. $V_{\rm o}$ consistent with very uncertain $V_{\rm opt}$ ($-26.0\pm40.0$ [kms$^{-1}$]{}).

091.6$-$04.8 (K 3-84) Flat-topped profile. $V_{\rm opt}$ is unknown.

094.5$-$00.8 (K 3-83) Asymmetric or double-peaked profile, affected by IS contamination on red side; dip at $V = -57 $ [kms$^{-1}$]{} and just beyond the red wing are IS. $V_{\rm opt}$ is unknown.

104.4$-$01.6 (M 2-53) Steep-sided, double-peaked profile. Deep IS dip at $V =
-43 $ [kms$^{-1}$]{} affects the extreme red wing of the profile. $V_{\rm o}$ consistent with very uncertain $V_{\rm opt}$ ($-62.0\pm40.0$ [kms$^{-1}$]{}).

107.6$-$13.3 (Vy 2-3) Tentative 5$\sigma$ detection. Line is narrow for a PN but it could be
