Large scale [CII] emission from the OMC
Listed in IVOA Registry (Virtual Observatory)
The [CII] 158um far-infrared (FIR) fine-structure line is one of the dominant cooling lines of the star-forming interstellar medium (ISM).
Description
Hence [CII] emission originates in, and thus can be used to trace a range of ISM processes. Velocity resolved large scale mapping of [CII] in star forming regions provides a unique perspective on the kinematics of these regions and their interactions with the exciting source of radiation.
In this paper we explore the scientific applications of large scale mapping velocity resolved [CII] observations. With [CII] observations we investigate the influence of stellar feedback on the ISM. We present the details of observation, calibration and data reduction using a heterodyne array receiver mounted on an airborne observatory.

A 1.15 square degree velocity resolved map of Orion molecular cloud centred on the bar region was observed using the upGREAT heterodyne receiver flying on-board the Stratospheric Observatory for Infrared Astronomy (SOFIA). The data was acquired using the 14 pixels of the German REceiver for Astronomy at Terahertz Frequencies (upGREAT) observing in an on-the-fly mapping mode. 2.4 million spectra were taken in total. These spectra were gridded into a three dimensional cube with a spatial resolution of 14.1 arcseconds and spectral resolution of 0.3km/s.
