Another data loading issue that causes problems and is easily overlooked is scaling issues. If the expected amplitude range is not encountered and the data is scaled to integer values for 8-bit or 16-bit resolution, something similar to clipping may occur. Figures 1–8 show such an example using a different data set than the Stratton data set shown in Part 1 (TLE, November 2001). The original SEG-Y on tape had amplitudes several orders of magnitude lower than expected, so when the data...
