BSTK

Stacks all the traces in a gather, outputs the same trace repeatedly, number in = number out. Command line argument is the input file name. Figure 84 (A) shows the reference phone recording for each source effort of a down-hole survey. While repeatable, there is some variation as the source compacts the ground. (B) shows the average of all the source efforts estimated by the sum of all the traces in (A). The summing is called a stack.
