Paper Abstract

The faint object spectrograph (FOS) is a highly efficient, fixed format spectrograph using a CCD detector and aimed at low resolution (15-20Å fwhm) spectrophotometry over the range 4000 to 10500K. The overall efficiency including atmosphere and telescope absorption is 12% at 7000K and a zenith distance of 27.5. It has a fixed spectrum format and is provided with an extensive set of on-line data reduction and analysis operations.
