Cep E outflow emission observed in the CO J = 2–1 line with the PdBI at 1″ resolution (contours) and with IRAC/Spitzer H₂4.5 μm line (color). Each panel shows the emission associated with each of the three outflow components identified: (left) outflow cavity walls emission, integrated between −15.2 and −8.7 km s^-1 in the southern lobe (blue contours) and between −2.2 and −8.7 km s^-1 in the northern lobe (white contours); (center) jet emission integrated between −135 and −110 km s^-1 and between +40 and +80 km s^-1 towards the southern (blue contours) and northern lobes (white contours), respectively; (right) HH377 bowshock emission integrated between −77 and −64 km s^-1 (blue contours). First contour and contour interval are 20% and 10% of the peak intensity, respectively.
