**orbdim
in=**orbit [parameter=value]

Other methods, such as SALI (see Manos & Athanassoula), exist.

*orbdim* needs a lot of data before the exponent can be reliably determined.
In practice a 3 dimensional orbit is excluded from this analysis. It can
be done with 2 dimensional orbits though.

LIs: Lyapunov Indicators (there are several) MEGNO: Mean Exponential Growth factor of Nearby Orbits SElLCE: Slope Estimation of the largest Lyapunov Characteristic Exponent SALI: Smaller ALignment Index GALI: Generalized ALignment Index FLI: Fast Lyapunov Indicator OFLI: Orthogonal Fast Lyapunov Indicator SD: Spectral Distance SSNs: dynamical Spectra of Stretching Numbers RLI: Relative Lyapunov Indicator
