Sounds great! I’ll admit that I’m not confident in this area either, but my reading of the documentation suggests that this is the right approach: the damping controls the square norm of x. By keeping it small (with large damping), you force the elements to be non-negative.
The approach looks OK, I am just a bit "unconfident" about tweeking a factor to get the image I am expecting. Not very scientific when the resulting image has to used as input for quantitative analysis.
I hope the final picture looks good now! =) If you get a nice result, I suggest you write a blog post about it, with pictures. It sounds like a very cool use of SciPy, and would be a valuable addition to writeups about it!
This will be part of the documentation of pyFAI by the end of the year: http://pyfai.readthedocs.io/en/latest/usage/tutorial/index.html To Stefan, I am sorry I forgot about your PhD work. I will check again your work, last time it was a different topic :) Cheers, Jerome
