Description:                      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/) as well as the FFTW3 library (http://www.fftw.org/).
        Both librairies 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) 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
        
        Change history:
        1.6 (29/11/2020): module made compatible with NFFT version 3.5.3
        1.5 (2/02/2020): module interface is now based on Cython, module now compatible with python 3
        1.4 (11/04/2019): interface of nfft() changed, this function can now compute an over-sampled fourier transform
        1.3 (10/04/2019):  correct a bug that lead to over-estimate the frequency by a relative factor of 1e-5
        1.2 (4/06/2013): 
        1.1 (18/01/2013):
        1.0 (3/01/2013): initial version
