## 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)
