This program combines the sampled data to generate the Gn 's for a selected subset of the particles.
Program prints the mean residual for each Z level and flags components which have no values.
See the warnings about recycling below. The resolution is decreased until this criterion is met. A summary of the eigenvalue spectrum is printed at the end of the run. When there is insufficient data to complete the solution of the linear equations to the degree defined by the eigenvalue limit, the program recycles to a lower number of parameters. In practice this means that some of the coefficients of the BG expansion will not be calculated.
