4. Conclusions

We have presented 12 CO J [FORMULA] 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 [FORMULA] [FORMULA] and a dynamical timescale of [FORMULA] 1 [FORMULA] 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.
