Resumen:
A method of classifying generic orbits in arbitrary 2D and 3D potentials is presented. It is
based on the concept of spectral dynamics introduced by Binney & Spergel that uses the
Fourier transform of the time series of each coordinate. The method is tested using a number of
potentials previously studied in the literature and is shown to distinguish correctly between
regular and irregular orbits, to identify the various families of regular orbits (boxes, loops,
tubes, boxlets, etc.), and to recognize the second-rank resonances that bifurcate from them.
The method returns the position of the potential centre and, for 2D potentials, the orientation of
the principal axes as well, should this be unknown. A further advantage of the method is that it
has been encoded in a FORTRAN program that does not require user intervention, except for fine
tuning of search parameters that define the numerical limits of the code. The automatic
character makes the program suitable for classifying large numbers of orbits.
