Apply a Gaussian taper to a stratigraphic series
gausTaper(dat,alpha=3,rms=T,demean=T,detrend=F,genplot=T,verbose=T)
Stratigraphic series for tapering. First column should be location (e.g., depth), second column should be data value. If no data is identified, will output a 256 point taper to evaluate the spectral properties of the window.
Gaussian window parameter: alpha is 1/stdev, a measure of the width of the Dirichlet kernel. Larger values decrease the width of data window, reduce discontinuities, and increase width of the transform. Choose alpha >= 2.5.
Normalize taper to RMS=1 to preserve power for white process? (T or F)
Remove mean from data series? (T or F)
Remove linear trend from data series? (T or F)
Generate summary plots? (T or F)
Verbose output? (T or F)
