Why are the results I'm obtaining in my simulation different from the seis_data in OPENFWI? #7

  1. When I perform forward modeling using the parameters from the OPENFWI paper, the obtained seis_data has an opposite sign to what is expected.

  2. After taking the negative of my seis_data, it becomes quite similar to the data provided by OPENFWI. However, the Frobenius norms of the two datasets still remain significantly different.

  3. When I perform forward modeling using the same parameters with Deepwave, the results obtained are consistent with mine.
