                 RESTRAX ver. 4.8.1, March 2005
-----------------------------------------------------------------
RESTRAX is a program package for Monte Carlo simulations and data
analysis for three-axis neutron spectrometers (TAS). It is equiped with
highly optimised ray-tracing code for simulation of TAS resolution
functions and additional tools for data analysis. It provides graphical
representation of resolution functions as well as both simulated and
experimental scattering functions. The non-linear least-squares fitting
routine is available with variety of scattering models and a possibility
to add other models created by users as a library linked dynamically to
the main program.

Mersenne-Twister - random number generator developed by Makoto Matsumoto
and Takuji Nishimura [ACM Trans. on Modeling and Computer Simulation
Vol. 8, No. 1, Januray pp.3-30, 1998] and coded to Fortran by Hiroshi
Takano. http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/emt.html. This

TRAX - the program written by M.Popovici, A.D.Stoica and I.Ionita [J.
Appl. Cryst. 20 (1987) 90-101] for analytical calculation of
resolution functions and optimisation of TAS. In RESTRAX, parts of this
code is used to calculate the TAS resolution function analytically in
gaussian approximation.

PGPLOT - the Fortran graphics library written by Tim Pearson, California Institute of Technology, provides graphical representation of results (http://www.astro.caltech.edu/~tjp/pgplot).
