Steve,
I tried to simulate what I think you want to accomplish.
Basically it's what I think is called a "walkaway" shoot in exploration.
The cable is stationary and the shots move.
The following is an example of a walkaway. The trick is to use geom
type 1, which adds DFLS to the previous shot's x-coordinate to obtain the
x-coordinate for the current shot. Then use GXP to establish the receiver
x-coordinates.
The example below moves the shots around alot in order to show that
the RP calculation is ok and that dead traces are inserted when no
traces contribute to an RP.
