   PR #   136
   A665 is one of the distant clusters of galaxies and is suitable for
   measurement of Hubble constant from X-ray properties and the
   Sunyaef-Zel'dovich effect.Both for this purpose and for general
   cluster sciences such as mass of the cluster, its metalicity, its
   state of evolution and the detection of coolingflow, we need accurate
   spatially resolved X-ray spectra.
