Kernel example for Tape-Liu-Tromp (GJI 2007).

TO RUN:

0. Read the user manual in SPECFEM2D/doc/manual_SPECFEM2D.pdf

1. in SPECFEM2D root directory, configure, e.g., 
   > ./configure FC=gfortran

2. modify setup/constants.h file, setting USER_TO = 48.0 s

3. compile:
   > make all

4. run mesher and solver for forward wavefield:
   > cd EXAMPLES/Tape2007_kernel/
   > ./process.sh

5. compute adjoint source:
   > rm -rf xadj_seismogram ; gfortran adj_seismogram_Tape2007.f90 -o xadj_seismogram
   > xadj_seismogram

6. change Par_file with save_forward = .false. and SIMULATION_TYPE = 2

7. run adjoint simulation:
   > ./process_kernel.sh
