v0.1.3-alpha.1 - Cubic spline velocity function inversion

Cubic spline velocity function inversion (Development version of creVelocityInversion package)

• Changed

• Resolve #23

• Use previous spline function as input: Use the previous velocity cubic spline function as input
  for the next iteration in the velocity inversion algorithm. 675d7a7

• Use cubic spline velocity model in inversion instead of a constant velocity gradient model 15c7b55

v0.1.2-alpha.1 - Velocity inversion of a linear velocity gradient model

Development version of creVelocityInversion package

• Added

  • Velocity function to update the velocity gradient to simulate a velocity varying with depth model and evaluate if the NIP sources converges to the reflector interfaces 2c306e3

• Changed

  • Run inversion in looping #20 Run the velocity inversion in a loop using the prevous optimal model as input for the next iteration 87a0567

• Removed

  • Remove program sfniptimecurve and sfgetbetaangle: Those were test programs and there is no need for them anymore 8b0b723

  • Remove useless experiments from experiments directory: The inversion strategy has changed from diffraction simulation to ray tracying algorithm and NIP tomography be73a35

v0.1.1-alpha.1 - Development version with TDD tests

• Added

  • This version uses the velocity inversion algorithm from Cameron (2008) to obtain depth velocities from time migrated velocities.

  • Diffraction simulation and migration are done in functions defined in 'diffSimulationAndMigration.py' recipe. Those function have unit tests in TDD directory.

v0.1.0-alpha.1 - Scratch of the full velocity inversion algorithm

• Added

  • Raytracer study, simulate a point source inside the model and get rays escape values Resolve #5 b7154f9

  • Pre-stack velocity analysis with velocity continuation 7cf63ec

  • Iterative picking e44af5f

  • Generate simulated diffraction hyperbolas in a loop in iterative picking 0fca09c

  • Scratch of the velocity inversion algorithm using diffraction focusing migration Resolve #2 42c68d5
