EXERCISE
In this part, your task is to apply the workflow explained above to a different CMP
gather that requires different parameters. The same workflow should work here, but
you need to observe that the CMP gather used for this exercise has shallow events.
This means that, after applying NMO correction, amplitudes at far offstes of the
shallow events get stretched. Therefore, an additional step is required for this CMP.
We need to mute the distorted amplitudes. The mute is already applied in the
SConstruct.
1. Display the CMP gather after NMO with and without mute applied by running
