gausTaper: 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)
