This directory contains the source code, documentation, and some input and output
of a program used for numerical investigation of tagged particle diffusion in 1 dimension.

The documentation (brown1d.ps) is outdated: it does not describe late features such as automated
asymptote fitting, and does not describe the usage of the program. A new version is under construction.
Meanwhile, the input and output files are more-or-less self-explanatory.
Those who speak Hungarian will understand more.

An exposition of the results will be available soon in a research paper titled
"On the zero mass limit of tagged particle diffusion in the 1-d Rayleigh-gas"
by Peter Balint, Balint Toth and Peter Toth.
