-The subscript s100 is the same set of simulations but scaled down in size
-by a factor of 100. This requires increasing the source frequency content
-and decreasing the time step.
+The example currently only generates the (synthetic) seismograms associated with the PSV example in Figure 7b and the SH example in Figure 2b.
-In Tromp2005 there is a time shift of 8 s before the source starts.
