description: idpeaks takes two files giving the locations of spectral peaks for
a two dimensional coupled oscillator[5] and identifies the peaks as resonances
of the form where i, j, and k are integers.
It is assumed that the values of and are given by the highest
peaks in the respectively files.
files: xpeaks-filename and ypeaks-filename are mpl-format files containing (tune, amplitude)
pairs for spectral peaks.
options:
order
Specifies the maximum value of the order, k, of the resonances that will be considered.
resolution
Specifies how close must be to k for the program to consider
the peak as identified.
draw_input
Specifies the names of two files into which will be placed draw commands for labeling
the frequency spectra with the resonance line identifications. draw is a graphics interpreter
that incorporates mpl as a subprogram.
