Scientific paper

An extensive velocity resolved survey at 1 minute resolution of 158 microns CII fine structure line emission in the central 50 pc of the Galaxy is reported. Spectra were taken toward about 625 positions with a new imaging far infrared spectrometer on board the NASA Kuiper Airborne Observatory. Observations and results are given and discussed under the following headings: mass and luminosity of CII in the central 50 pc; CII emission from the SgrA complex; the relationship between SgrA and the radio arc; CII emission and galactic center molecular clouds; and mass accretion into the circumnuclear region.
