Starlab version 4.4.1
    program created on Apr 27 2005 at 22:57:22
    source file     /home/steve/starlab/src/node/dyn/hdyn/util/hsys_stats.C

This is the "hdyn" (kira output) version of sys_stats.  It contains
all of the "dyn" sys_stats functionality (and will work with standard
dyn data files), but includes additional functions specific to the
hdyn class.

Print out various diagnostic statistics on the input system.
These include:

        system time, number, mass, mass distribution;
        relaxation time;
        system energy;
        core parameters;
        lagrangian radii for quartiles [default], for ten-percentiles,
        and for "special" choice of Lagrangian masses, currently 0.005,
        0.01, 0.02, 0.05, 0.1, 0.25, 0.5, 0.75, 0.9;
        mass distribution by lagrangian zone;
        anisotropy by lagrangian zone;
        binary parameters.

In addition, Lagrangian radii are written to the root dyn story.
If N^2_ops	is selected, then core parameters and particle densities
are also written to the root and particle dyn stories.

If N^2_ops is selected, Lagrangian radii are computed relative to
the density center, as are binary radial coordinates.  Otherwise,
the modified center of mass (center of mass with outliers excluded)
is used.
       	
Options:
             -b    specify level of binary statistics [2]
                   0: none
                   1 (or no arg): short binary output
                   2: full binary output
             -e    recalculate the total energy (even if -n is no) [yes]
             -l    specify percentile choice [2]
                   0: quartiles (1-3)
                   1: 10-percentiles (10-90)
                   2 (or no arg): nonlinear Lagrangian masses
                   (0.5, 1, 2, 5, 10, 25, 50, 75, 90%)
             -n    perform/don't perform actions requiring O(N^2)
                   operations (e.g. computation of energy and core
                   radius; see -e) [no]
             -o    pipe system to cout [no]
