Fig. 1
Large-scale view of the L1157 outflow. The main frame shows a superposition of the CO map from Bachiller et al. (2001) (contours) and the 3.6 μm Spitzer image of Looney et al. (2007). The inset shows the inner outflow according to the interferometric CO map of Jørgensen et al. (2007). The star symbol represents L1157-mm and the three circles represent the positions and beam sizes of our SiO(5–4) observations.
