   We are aiming to construct the local X-ray Temperature Function of the
   brightest clusters which can be usable for further investigation of
   cosmology. From ROSAT All Sky Survey, Reiprich & Boehringer (Co-Is of
   this proposal) compiled an X-ray flux-limited cluster sample which has
   the highest completeness ever achieved. By the ASCA observations
   proposed here, temperature measurements for the complete sample will be
   completed. Then we can construct the cluster temperature function with
   the highest accuracy, which will give a strong constraint on
   cosmological models.
