Query: Spline histogram method for reconstruction of probability density
  function of clusters of galaxies   We describe the spline histogram algorithm which is useful for visualization
of the probability density function setting up a statistical hypothesis for a
test. The spline histogram is constructed from discrete data measurements using
tensioned cubic spline interpolation of the cumulative distribution function
which is then differentiated and smoothed using the Savitzky-Golay filter. The
optimal width of the filter is determined by minimization of the Integrated
Square Error function.
  The current distribution of the TCSplin algorithm written in f77 with IDL and
Gnuplot visualization scripts is available from
