Window a GH structure and extract data
Window a time slice of seismic data and extract from a GH structure.
WINGH(GH, sel = 1, WIN = c(0,1) )
GH |
RSEIS seismic list |
sel |
Select which traces to extract |
WIN |
Time window to extract (seconds from the beginning of the first trace.) |
Preserves the data structure of the GH list. The purpose of this function is to extract a small subset of data from a larger data set (or longer time series) for subsequent processing.
New GH structure.
