pynfftls 1.2

Fast Lomb-Scargle periodogram using Non-equispaced Fast Fourier Transform (NFFT) by B. Leroy

PyNFFTls

This Python module provides the Fast Lomb-Scargle periodogram
developed by B. Leroy (2012, Astron. Astrophys. 545, A50)

It is based on the Non-equispaced Fast Fourier Transform (NFFTn http://www-user.tu-chemnitz.de/~potts/nfft/download.php) as well as the FFTW3 library (http://www.fftw.org/).
Both libraries must be installed.

Calling sequence:
    (f,p) = period(t,y,ofac,hifac)

For more details, see the associated documentation
For a complete example, see nfftls_test.py


This Python module also provides the following methods:
- the Non-equidistant Fast Fourier Transform (NFFT, see http://www-user.tu-chemnitz.de/~potts/nfft/) of a time series:
    (f,A) = nfft(t,y,p,d)
For more details, see the associated documentation

- the Discrete  Fourier Transform  (DFT) of a time series:
    A = dft(t,y,f)
For more details, see the associated documentation

For a complete example, see nfftls_test2.py
