2SHH]8YXSVMEP1ERYEPStep 7We can produce a composite image to check on the exact placement andorientation of the fault. To do this select Geophysics>Difference WithReference>Magnetics and reload in the newly created .MAG file. Theresulting image is the reference image subtracted from the model image. Boththe model and fault positions show up quite clearly in this image, sorepositioning and re-orienting the fault becomes quite simple. This differenceimage is also available in the Preview window, but is much smaller and harderto deal with. Once the fault is positioned and oriented correctly, you can start toworry about the Ellipsoid Axis dimensions so that the shape of the fault blockmatches the observed data.
