General picture of I22134 according to the kinetic properties of the molecular line observations, not scaled. The blue ellipses and block indicate the dense clouds traced by different molecules as labeled in the figure. The two green clouds mark the N₂D⁺ cores, the orange arc shows the PDR traced by C₂H, the light blue blocks show the possible shocked emission traced by CH₃OH, the small stars the B stars in the cluster (Kumar et al. 2003), the big filled star the UCHii region VLA1, the small filled star marks VLA2, the black stars the millimeter cores from our observations. The antenna shows our observation point.
