Madagascar tutorial: Field data processing

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. Change directory to ex directory

   bash$ cd ../ex
   

2. Display the CMP gather after NMO with and without mute applied by running

   scons nmo1-nmo.view
   

3. Your task is to add the necessary code to attenuate multiples for this CMP. The same work flow used in the SConstruct file under demo directory should work here with only changes to
   • x0
   • t0
   • v0
     where it says CHANGE ME in the comments

   Hint: You will need to copy part of ../demo/Sconstruct to this SConstruct file.
