gausTaper: Apply Gaussian taper to stratigraphic series

In astrochron: A Computational Tool for Astrochronology

Apply Gaussian taper to stratigraphic series

Description

Apply a Gaussian taper to a stratigraphic series

Usage

gausTaper(dat,alpha=3,rms=T,demean=T,detrend=F,genplot=T,verbose=T)

Arguments

dat	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.
alpha	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.
rms	Normalize taper to RMS=1 to preserve power for white process? (T or F)
demean	Remove mean from data series? (T or F)
detrend	Remove linear trend from data series? (T or F)
genplot	Generate summary plots? (T or F)
verbose	Verbose output? (T or F)
