Scratch of the tests in datamisfit directory: Calculate the datamisfit between a pre calculated traveltime curve and modeled traveltime with the new version of the program sfniptimecurve Copy the program sfniptimecurve source file to build the new version and keep the old version
Store true model (t,x) coordinates in td and xd vectors to be used to calculate data misfit after modeling
Data misfit will be used as optimization criteria for velocity inversion, so store it in tmis vector
Use a function to update de velocity in each iteration of the ray tracing process and calculate the data misfit in time and x coordinates
The program sfstereoniptomo uses the NIP sources to trace rays from them to acquisition surface in order to obtain the traveltime curve and to compare it with the CRE traveltime calculated values. The data misfit will be used to update the velocity model. We also add the program sfgetparameter to extract the parameters from parameters cube for (t0,m0) location given
Picking of 26 nip sources and experiment repetition
Add 26 nip sources for the stereoniptomo experiment and try to recover the reflector shape
This script prepares the txt files generated by sfipick in a format readable by sfdd that convets them to RSF
Backup of the input files needed to run this test and a setup SConscript. Run 'scons -f SConscript1' to setup input files and allow the test
Generate the GDB version of sfgetparameter with 'make getparameter.x' command
Utility python script to plot the NIP sources using depth coordinates and to plot m0s in the acquisition surface. To setup input files run 'scons -f SConscript2' and after run the viewNipSources.py script. It will load generated files and plot sources using matplotlib python library
sfstereoniptomo is a program that does the forward modeling for a set if NIP sources given and normal ray angles
Coordinates of the nipsources are optimized using VFSA and summation of time misfit root mean squared criteria
Plot the true interface using the program viewNipSources.py
The program sfnipmodsetup uses t0/2 instead of t0 and the casting is corrected
Use VFSA optimization to locate nipsources. Do the process for each nipsource at time
Use Makefile to run the experiment: 'make help' to get help. This experiment uses a two interfaces model with sfstereoniptomo
Output the inverted velocity model after sfstereoniptomo finishes
