... The FOS employed one of six basic data taking modes to acquire science data: . Spectrophotometry (ACCUM). ... Image. ... ACCUM was by far the most commonly used observing mode. ... In IMAGE mode observations both the number and length of rasters and the y- position of each raster could be specified, so that: 1) a white-light image of all or a portion of the aperture was possible with the MIRROR, and 2) spectra from different portions of the aperture were sampled with a disperser. ...

HI spectral-line observations of galaxies (Karen O'Neil) .
