## Integration Parameters

INTEGRATION TIME. Here you specify how many years into the future
the resonant perturbation should be followed. Be careful in choosing this
parameter as it is directly correlated to how long you will wait before
seeing a plot! A good strategy is to try a short integration time first
to get an idea of how fast the program is.
FREQUENCY. This number determines how often a point along the
orbit is saved to disk. A larger number yields a more accurate plot at
the expense of plotting time and disk space. You want to choose the
largest number that yields a reasonably accurate plot. Experiment!
