4. Conclusions

We have presented ¹² CO J 3-2 high-resolution observations of the HH 1-2 region and our major conclusions are:

1. VLA 1 does indeed possess an outflow. This outflow is extremely weak, compact and young. We derived a total mass of 1.1 and a dynamical timescale of 1 yr. This outflow is clearly distinct from the stronger VLA 3 outflow. The existence of this outflow suggests that other sources that are currently classified as non-outflow sources might have very weak and compact outflows not yet detected.
2. VLA 3 is confirmed as a source with a more extended and powerful outflow. This outflow is almost 100 times more massive than the VLA 1 outflow.
