   ROSAT reported that the spectrum of RX04591+5147 is represented by 0.5
   keV thinthermal emission from a cosmic abundance plasma in the
   ionization equilibrium state, while Ginga detected a hard component
   (kT=8 keV) as well as the soft component. A high quality spectroscopic
   observation in the 0.5 - 10 keV band is required. Comparison between
   the spectral parameters of the central region and those of the rim
   region isconsidered to be very important.
