# Description of the program: fsle

The program estimates the finite size Lyapunov exponents as proposed in Aurell et al..
Remark: I should mention that this program is still in an early beta state.

## Usage:

fsle [Options]

Everything not being a valid option will be interpreted as a potential datafile name. Given no datafile at all, means read stdin. Also - means stdin

Possible options are:

Option | Description | Default
--- | --- | ---
-l# | number of data to be used | whole file
-x# | number of lines to be ignored | 0
-c# | column to be read | 1
-m# | embedding dimension to use | 2
-d# | delay to use | 1
-t# | window around the reference point which should be omitted | 0
-r# | minimal length scale for the neighborhood search | (std. dev. of data)/1000
-o# | output file name | 'datafile'.fsl (or stdin.fsl if data was read from stdin, without -o: stdout)
-V# | verbosity level 0: only panic messages 1: add input/output messages | 1
-h | show these options | none

## Description of the Output:

- First column: length scale in natural (data) units
- Second column: Estimate finite size Lyapunov exponent
- Third column: Number of points used for this length scale
