Understanding the underlying shocks is necessary to explain how jet and outflow systems are launched, and to quantify their chemical and energetic impacts on the surrounding medium. We performed a high-spectral resolution study of the [OI]63um emission in the outflow of the intermediate-mass Class 0 protostar Cep E-mm. The goal is to determine the structure of the outflow, to constrain the chemical conditions in the various components, and to understand the nature of the underlying shocks, thus probing the origin of the mass-loss phenomenon. We present observations of the OI 3P1 -> 3P2, OH between 2Π1/2 J=3/2 and J=1/2 at 1837.8GHz, and CO (16-15) lines with the GREAT receiver onboard SOFIA towards three positions in the Cep E protostellar outflow: Cep E-mm (the driving protostar), Cep E-BI (in the southern lobe), and Cep E-BII (the terminal position in the southern lobe). Description: All spectra shown in Fig. 2 are provided in FITS format at their nominal spectral and spatial resolution x-axis is the lsr velocity (in km/s) y-axis is the main beam temperature (in K) they were obtained with the SOFIA-GREAT receiver (see Table 2 for details): - the CO, OH, and OI spectra shown in the upper panel (Cep E - mm position) are in the co-cepe-mm.fits, oh-cepe-mm.fits, and oI-cepe-mm.fits files; - the CO, OH, and OI spectra shown in the middle panel (Cep E - BI position) are in the co-cepe-BI.fits, oh-cepe-BI.fits, and oI-cepe-BI.fits files; - the CO, OH, and OI spectra shown in the upper panel (Cep E - BII position) are in the co-cepe-BII.fits, oh-cepe-BII.fits, and oI-cepe-BII.fits files.
