Aims. In the framework of the Water In Star-forming regions with Herschel (WISH) key program, several H2O (Eu > 190 K), high-J CO, [Oi], and OH transitions are mapped with Herschel-PACS in two shock positions along two prototypical outflows around the low-luminosity sources L1448 and L1157. Previous Herschel-HIFI H2O observations (Eu = 53−249 K) are also used. The aim is to derive a complete picture of the excitation conditions at the selected shock positions.
