      This collection consists of HISCALE W ion counts from the                              
      Ulysses Jupiter encounter 1991-Dec-31 to 1992-Feb-16. This                             
      includes 1 hour averaged inbound cruise data (1991-12-31 to                            
      1992-02-01), and 15 minute averaged encounter data (1992-02-02                         
      to 1992-02-16).                                                                        
                                                                                             
      The Heliosphere Instrument for Spectra, Composition, and                               
      Anisotropy at Low Energies is designed to make measurements of                         
      interplanetary ions and electrons throughout the entire                                
      Ulysses mission.                                                                       
                                                                                             
      The ions (Ei > 50 keV) and electrons (Ee > 30 keV) are                                 
      identified uniquely and detected by five separate solid-state                          
      detector telescopes that are oriented to give nearly complete                          
      pitch-angle coverage from the spinning spacecraft.                                     
                                                                                             
      Ion elemental abundances are determined by a del E vs E                                
      telescope using a thin 5 micrometer front solid state detector                         
      element in a three element telescope.  Experiment operation is                         
      controlled by a microprocessor-based data system.                                      
                                                                                             
      Inflight calibration is provided by radioactive sources                                
      mounted on telescope covers which can be closed for                                    
      calibration purposes and for radiation protection during the                           
      course of the mission.                                                                 
                                                                                             
      Ion and electron spectral information is determined using both                         
      broad-energy-range rate channels and a 32 channel pulse-height                         
      analyses (channels spaced logarithmically) for more detailed                           
      spectra.
