Fragmented and irregularly spaced\ndata can be processed in almost all methods. Both, FFT as well\nas LOMB methods take multivariate data and return standardized\nPSD. For didactic reasons an analytical approach for\ndeconvolution of noise spectra and sampling function is\nprovided. A user friendly interface helps to interpret the\nresults.", "License": "GPL-2", "RoxygenNote": "7.1.0", "NeedsCompilation": "no", "Packaged": { "Date": "2026-05-12 07:41:10 UTC", "User": "root" },
