Hi Dr. Alan,
Thank you for your great contributions to seismic imaging and inversion.
I find that Deepwave does not seem to support propagation of first order acoustic equations. So I tried to write…

Hi Daniel,
I recently came across your excellent open-source code, DENISE Black Edition, which I believe will be extremely helpful for my master's thesis project, as I need to perform FWI and LSRT…

Hi Alan,
Thank you for making a great seismic modeling and inversion package. I have followed the code GAN for FWI which he used your wave propagator code for generate the data as given in the foll…

Hi,
I'm trying to calculate seismic tomography based on first arrivals.
It seems that some points are inaccurate picked and the apparent velocity max val is about 31000 …
