SPECTROSCOPY CONTROL STATEMENTS

The spectroscopy control statements are new to ATIS2000 and thus should be considered experimental. Since the data is taken using a CCD camera these statements are only concerned with the setup and control of the spectrometer. The actual data will be taken using the 500 series of CCD commands. The ATIS output file will contain FITS file names as pointers to the CCD data files. The data files will conform to the CCD file naming conventions (page 56 ).
