SUGAUSSTAPER - Multiply traces with gaussian taper
sugausstaper < stdin > stdout [optional parameters]
Required Parameters:
<none>
Optional parameters:
key=offset keyword of header field to weight traces by
x0=300 key value defining the center of gaussian window",
xw=50 width of gaussian window in units of key value
Notes:
Traces are multiplied with a symmetrical gaussian taper
w(t)=exp(-((key-x0)/xw)**2)
unlike "sutaper" the value of x0 defines center of the taper
rather than the edges of the data.
