   PR # 41240
   We propose re-observation of the distant cluster of galaxies,
   Cl0016+16 which observed Sunyaev-Zel'dvich. From the results of the
   previous observation, this cluster may be show the presence of
   temperature drop in the envelope of the cluster. The error of the Gas
   density profile is very large due to poor statistics in the envelope.
   This cause large uncertainty for the measurement of the Hubble
   constant. In the previous observation, Fe-K emission line couldn't be
   detected clearly and only the upper limit of the iron abundance was
   obtained. If Fe-K line could be detected with highly confidence, it
   give us many information for chemical evolution because of that
   distance. Then the re-observation of Cl0016+16 is important for
   cosmology and chemical evolution of cluster of galaxies.
