DATA DESCRIPTION
================

Data stored here are human-readable. They are compatible with gnuplot.
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.


Evolution of an electron bunch represented by 401 particles with initial mean
momentum \bar{p} = 2000 (~ 1 GeV) and relative spread 20% in the collision with a
counter-propagating N-cycle plane-wave laser pulse, with N a_0^2 = 9248. Positive
and negative chirp rate \Delta = +/- 0.5 has been used. Files with the .dst file
extension are the particle distribution f(\phi,p). Each snapshot during the \phi
evolution is commented with an ID and average properties. Snaphots are separated by
a blank line. Files with the .stats extension contain statistics of the electron
bunch.
