    PR # 31110                                                                   
     We propose 80ks observation of typical S0 galaxy NGC3065. We can dete       
     rmine the abundance of hot gas of the galaxy and compare it with that       
      of elliptical galaxies and then  determine the ratio of Type Ia SN a       
     nd Type II SN. Then we can study the difference of population of star       
     s of S0 galaxies and ellptical galaxies.
