摘要：

The ESA Herschel Spectral and Photometric Imaging Receiver (SPIRE) Fourier Transform Spectrometer (FTS) Spectral Feature Finder (FF) project is an automated spectral feature fitting routine developed within the SPIRE instrument team to extract all prominent spectral features from all publicly available SPIRE FTS observations. In this work, we demonstrate the use of the FF information extracted from three observations of the edge-on spiral galaxy NGC 891 to measure the rotation of NII and CI gas at far-infrared frequencies in complement to radio observations of the [HI] 21-cm line and the CO(1-0) transition as well as optical measurements of H alpha. We find that measurements of both NII and CI gas follow a similar velocity profile to that of HI and H alpha showing a correlation between neutral and ionized regions of the interstellar medium in the disc of NGC 891.
