Query: Systematic effects in the interpretations of Cluster X-ray Temperature
  functions   The formation and evolution of clusters of galaxies are sensitive to the
underlying cosmological model. Constraints on cosmological parameters of cold
dark matter models have been derived from mass, temperature and luminosity
functions of clusters. We study the importance of including cluster formation
history and a correction for collapsed fraction of objects in determining the
cluster X-ray temperature function. We find that both effects are important. We
compare temperature functions obtained by using a power law approximation for
the mass variance normalized to X-ray clusters to those obtained by using a
COBE normalized full CDM treatment. We conclude that the temperature function
could be a powerful test on the average density of the Universe if we could
find the correct way of interpreting the data.
