First you will limit the propagation angles in the subroutine, and then you will modify the routine to handle //v(z)// | 10/21 | {{sep:courses:labs210:lab4_fortran.pdf|Lab4.pdf(fortran)}}, {{sep:courses:labs210:lab4_fortran.tar.gz|Lab4.tar.gz(fortran)}}, {{sep:courses:labs210:Lab4_matlab.pdf|Lab4.pdf(matlab)}}, {{sep:courses:labs210:Lab4_matlab.tar.gz|Lab4.tar.gz(matlab)}} | | | {{sep:courses:gif:lab4.gif}} | **Kirchhoff migration** | In this computer exercise you will modify the Kirchhoff migration and modeling subroutine that was presented in class.

| - | | {{sep:courses:gif:lab6.gif}} | **Phase shift downward and upward continuation** | In this exercise you are provided with a modified version of the phase shift migration and modeling programs found in // Basic Earth Imaging// (BEI). The program has been arranged so that it outputs snapshots of a wavefield as it is upward continued and downward continued. This week's programming task will be to add depth-variable velocity to the phase shift program. | | | | + | | {{sep:courses:gif:lab6.gif}} | **Phase shift downward and upward continuation** | In this exercise you are provided with a modified version of the phase shift migration and modeling programs found in // Basic Earth Imaging// (BEI).

The exercises come from BEI Section 10.4. You have to change the subroutine wavemovie to reproduce the movies from which the Figures in that section are taken. | | | | + | | {{sep:courses:gif:lab7.gif}} | **Finite difference wavefield extrapolation ** | In this lab we solve the parabolic wave-equation in 2-D by implicit finite-difference methods in frequency space.
