""" Fast algorithm for spectral analysis of unevenly sampled data
The Lomb-Scargle method performs spectral analysis on unevenly sampled
data and is known to be a powerful way to find, and test the
significance of, weak periodic signals. The method has previously been
thought to be 'slow', requiring of order 10(2)N(2) operations to analyze
N data points. We show that Fast Fourier Transforms (FFTs) can be used
in a novel way to make the computation of order 10(2)N log N. Despite
its use of the FFT, the algorithm is in no way equivalent to
