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) |
