Left: [O i] 63 μm integrated intensity map of the NGC 1333-IRAS4A and 4B outflows as obtained with Herschel-PACS (Nisini et al. 2015). The R1 position is shown with black and white circles just north of the source position; the smaller circle has a diameter of 6′′, and the larger circle has a diameter of 20′′. The protostellar positions are marked with stars. Right: spectra of selected transitions observed toward the R1 position in the NGC 1333-IRAS4A outflow. The [O i] and CO 16–15 spectra are observed with SOFIA-GREAT and the three H₂O spectra with Herschel-HIFI. Most spectra have been scaled by a factor as labeled. The source velocity, 7.5 km s^-1, is shown with a vertical dashed line, and the the HV component from 18−50 km s^-1 is highlighted in red. The beam size is shown on the right for each spectrum.
