   A963 is a distant cluster of galaxies whose redshift is z=0.2. It may
   have pointlike structure and no time variation. Such a point like and
   stable source is usefull for calibration of the position responce and
   point stread function of XRT.We expect its first accurate energy
   spectrum which is expected to have thermalemission feature with iron
   line and will help us to make a scenario how clustersevolved and when
   heavy elements dissipated into intracluster space.
