coincides with one of the main optical components.

055.6+02.1 (He 1-2) Flat-topped or concave profile with IS spike on the blue wing at $V = -8$ [kms$^{-1}$]{}. $V_{\rm opt}$ is unknown.

056.0+02.0 (K 3-35) Flat-topped profile with IS spike on the blue wing at $V = -8$ [kms$^{-1}$]{}. A CO spectrum obtained with the NRAO 12 m telescope was previously reported by Dayal & Bieging (1996). $V_{\rm o}$ agrees with H$_2$O maser velocities in the core region (Miranda et al. 2001). $V_{\rm opt}$ ($-9\pm2$ [kms$^{-1}$]{}, converted from LSR from Miranda et al. 2000) is offset by $\sim 12$ [kms$^{-1}$]{}.

060.1$-$07.7 (NGC 6886) $V_{\rm o}$ consistent with very uncertain $V_{\rm opt}$ ($-35.8\pm21.1$ [kms$^{-1}$]{}).

060.5$-$00.3 (K 3-45) Strong, double-peaked profile; narrow dip at $V =
   +15$ [kms$^{-1}$]{} and spike at $V = -32$ [kms$^{-1}$]{} are IS. $V_{\rm opt}$ is unknown.

062.4$-$00.2 (M 2-48) Strong, (probably) double-peaked profile, with IS contamination of red side; narrow dip at $V = -11$ [kms$^{-1}$]{} is also IS. $V_{\rm o}$ consistent with $V_{\rm opt} \sim -15$ [kms$^{-1}$]{} in core from Lopez-Martin et al. (2002).

067.9$-$00.2 (K 3-52) Double or single component with broad wings affected by strong IS contamination: dips in profile at $V = -17$, $-$4
