Tabla de apilamiento
A diagram showing the interrelationships among the traces from common-midpoint surveying; a graph of source-point location (s) versus geophone- group location (g) for a surface stacking chart, of s versus (s+g)/2 for a subsurface stacking chart. Used to determine the proper traces for stacking and for determining parameters for shifting traces (as in making static corrections). Components along various alignments represent common midpoint, common source, common geophone, or common offset. See Figure S-21.
