Left: CO J = 2–1 velocity-integrated emission of the protostellar jet observed with the PdBI. The emission is integrated between −135 and −110 km s^-1 and between +40 and +80 km s^-1 towards the southern and northern lobes, respectively. Right: the three kinematic components in the southern lobe of the Cepheus E outflow as seen by the PdBI at 1″ resolution in the CO J = 2–1 line: a) outflow cavity emission between −15 and −12 km s^-1 (color); b) HH377 bowshock emission between −77 and −64 km s^-1 (yellow contours); c) jet emission between −135 and −110 km s^-1 (blue contours). First contour and contour interval are 20% and 10% of the peak intensity, respectively. The white stars mark the location of the positions observed with SOFIA (−8.5″, −23″) and Herschel (HSO), IRAM, and JCMT (−12″, −18″). The beam width at half-power of SOFIA in the CO J = 16–15 and of HIFI in the J = 5–4 are drawn by a solid and a dotted circle, respectively.
