The modelling is first run on a single gather and then iterated on all available gathers. It requires as input shot or receiver gathers in SEG-Y format, along with first-break and reflection traveltime picks in ASCII format. If desired, also a migrated stacked section can be uploaded. In addition to the resulting reflector geometry the output data shows RMS error matrix, modelled pre- and post-stack reflection and azimuth coverage. The data provide also two example cases, a 3D synthetic model and a 2D real case. To use the code, open ReflectionModelling.m on Matlab© and modify the first part of the code with the desired input and variables, then, run the code and enjoy!
