      The Cross-Dispersed Echelle Spectrometer (CS2) is mounted               
      at the Coude f/32.5 focus of the 2.7m Harlan J. Smith                   
      telescope.  The following description is quoted from                    
      ''McDonald Observatory Facilities and Instruments''                     
      (Revised 28 Feb 2003), available from the McDonald                      
      Observatory web site at http://www.as.utexas.edu/mcdonald:              
                                                                              
        A high-resolution spectrometer  available with TK3,                   
        a thin, grade 1, Tektronix 2048 x 2048 CCD.  Two-                     
        pixel resolving powers in its two modes of operation                  
        are 60,000 (cs23) and 240,000 (cs21).  Two echelle                    
        gratings offer minimum inter-order separations of                     
        10.5 and 15.5 arcsec.  At R=60,000, data from the                     
        full bandwidth of 3,400-10,900 Angstroms are                          
        collected with the TK2048 CCD in as few as two                        
        exposures.
