Significant fluctuations in resulting CMF and Fe/Mg

[nedahejazi]

Hello @CaymanUnterborn

I have run "example_parallel_MR.py" without any changes, but I get different results for Fe/Mg and CMF every time I run the code. What is the reason? Is this because of degeneracy, number of iterations, or any other factor? Is there any solution for this problem?

@nedahejazi I'm not Cayman, but I think I can help here. Since you are running the file without any changes, I'm guessing the num_pts parameter (line 169) is still set to 5. If so, try changing the num_pts parameter (line 169) to something like 100 and see if the outputs are more consistent from one run to the next. Hope this solves the issue!

Hello @schulze61
Thank you so much for your help. I have tried 100 and even 200. I noticed 200 results in smaller fluctuations.
Actual Fe/Mg has a large uncertainty, but I assumed best-fit Fe/Mg is the one of importance.
