galaxy – representations of n–body simulations|
Files of this format are interpreted by galaxy(1) as describing
the inital condition of n–body simulations or the saved state of
simulation in progress. A galaxy file is a UTF stream of instruction
lines. The instruction is given by the first space delimited word.
The following instructions are accepted.
DT The rest of the line must contain a double–precision floating point number which determines the time–scale of the simulation.
