Synthetic seismograms

The synthetic data was generated using an explosive source and a Ricker2 wavelet with a fundamental frequency of 22.5 Hz. The source/receiver offsets ranged from 16 m (minimum offset) to 3.6 km (maximum offset). Figure 2 shows a shot gather at in-line location=5 km for each model; note that the events in model 2 are not perfect hyperboles due to the lateral velocity variations.
