PLUMIX
-------

package for generating of a mass segregated star cluster. It consists
of two programs:

mufu
----
generates a set of masses according to specified parameters of the mass
function and writes it to the standard output

plumix
------
reads numbers -- masses of individual stars -- on its standard input and
generates a mass segregated cluster, writing it to files 'n6.pos' and
'n6.check'. The first one is a list of stellar masses, positions and
velocities in the format suitable for Sverre Aarseth's NBODYx code; the
latter one is a human-readable dump of most of the quantities used in the
code. All quantities are in 'NBODY' units; total energy of the cluster
is implicitely set to 0.5.

For details see 'A new method to create initially mass segregated star
clusters in virial equilibrium', by Subr, Kroupa & Baumgardt, 2008

Compilation
-----------
Provided you have standard (GNU) development tools installed on your
computer, simply type 'make' in the directory where the sorce code
(plumix.c, mufu.c, rand.h, rand.c and Makefile) is saved. If everything
goes well, binaries 'mufu' and 'plumix' should be the output of the
compilation.

Usage
-----
Type 'mufu -h' and 'plumix -h' for available options. A standard hacker's
usage would look like:

mufu -N 1000 -m 0.1 -a -2.35 -m 100 | plumix -v -S 0.25

If something goes wrong, the procedure may be done in two steps for better
debugging. First run 'mufu' and redirect its output to standard file, check
it and then supply to 'plumix':

mufu -N 1000 -m 0.1 -a -2.35 -m 100 > mufu.out
cat mufu.out | plumix -v -S 0.25
