Orientation File

[pkoutla]

What is your question?
Hi there, and thanks for the code and all the effort! There are still some dark areas on how the file of orientations is created.

Below there are my questions-thoughts:

In the orientation file:

1. According to your example (i am running the 'ch1-1_Basics.ipynb'), why there are only 3 rows? --> I would expect 5 (at least one per formation type)
2. How did you find the XYZ? --> it seems to make no sense to me. Do they refer to the centroids of a plane?
3. Following the question above, there are 3 orientations; one for the fault, one from the left side of the fault and the other from the right side of the fault. Do we need to select the XYZ in a such deviation in order to capture their orientation (from G_x, G_y, G_z) in comparison with the fault? Will this make the fault normal or reverse? (please see the image attached and the arrows)

4. Is 'Azimuth' measured by the dip direction or the strike?
   Thank you very much for your time and i am looking forward for your answer!
