This is the ham particle tracing code. The input file is called
inputham.m, and it is meant to be an m-file so that it also can be
executed by matlab. In addition to the files included here, you will
also need the Tsyganenko model files, available at
http://geo.phys.spbu.ru/~tsyganenko/ and the Weimer model files, see
https://cedarweb.vsp.ucar.edu/wiki/index.php/Tools_and_Models:Empirical_Models

For running the T96 with the Weimer models, these files are: T96.f,
Geopack2008.f, weimer2k.f, and w2k.dat.

When the code runs, first the fields are computed on a grid. Since
the grid can be large, and this may take some time, parameters in the
input file may be set up so that the fields are saved in binary files
and so that these can be read the next time the program is used,
saving the time it would take to compute the fields all over again.

Some simple matlab plotting routines are found in the subdirectory
m_files.
