%description
On discrete data spectral analysis is performed by Fourier and Hilbert
transforms as well as with model based analysis called Lomb-Scargle
method. Fragmented and irregularly spaced data can be processed in almost
all methods. Both, FFT as well as LOMB methods take multivariate data and
return standardized PSD. For didactic reasons an analytical approach for
deconvolution of noise spectra and sampling function is provided. A user
friendly interface helps to interpret the results.
