   Notes to the table: $^{a}$ \citet{Wilson:2003fj}. The offset is with
   respect to \atwozero\ = 02:25:40.6, \dtwozero~=~+62:05:57. $^{b}$
   \citet{Olofsson:2003yq}. These authors use two different values for
   $N$(\htva) towards the (0, 0) position. The offsets are with respect
   to \atwozero~=~05:35:14.4, \dtwozero~=~--05:22:30. $^{c}$
   \citet{Klotz:2008lr}. The offsets are with respect to \atwozero~=~11:06:31.7, 
   \dtwozero~=~--77:23:32. $^{d}$
   \citet{Ristorcelli:2005fk}; Ristorcelli, private communication. The
   offsets are with respect to \atwozero~=~16:32:23.0, 
   \dtwozero~=~--24:28:40. $^{e}$ \citet{Persson:2009lr}, towards the PDR and the
   outflow. The offset is with respect to \atwozero~=~22:19:19.4,
   \dtwozero~=~+63:18:50. $^{f}$ Larsson et al. in prep., private
