DATA DESCRIPTION
================
Data stored here are human-readable. They are compatible with gnuplot and python.
Where there are multi-dimensional data, the last index/column varies most rapidly.
All data files contain a header (commented using #) which explains the data
layout.
For a discussion of the variables and numerical method used, please see:

Files have been sorted according to the theory with which the data was obtained:
Classical, Quasi-classical, or Stochastic. Provided in the files names are the
number of cycles in the pulse (N) and dimensionless intensity parameter (a), as
well as the laser polarisation (linear or circular).
In all cases, the initial electron had \gamma_0 = 2000.

Note that the quantity T is related to \chi through
\chi = 3T/(2\alpha)
where \alpha ~= 1/137 is the fine structure constant.
For the stochastic model, we provide the ensemble-averaged trajectory as well as
a representative single run. The ensemble size was 15000 electrons. In addition,
a list of all the radiated photons for the entire ensemble is included.

Note that the variable \tidle{\Omega} (column 2) in the radiation lists is a
dimensionless measure of the emitted photon energy. To obtain the energy, one
should multiply by
(1/2)mc^2
where m is the electron mass and c the speed of light (in vacuum).
