Dev/compton: Response interpolation, compton subtraction method and gauss smoothing

[fzeiser]

Issue by fzeiser Monday Sep 09, 2019 at 09:54 GMT Originally opened as https://github.com/oslocyclotronlab/ompy/pull/38

---

• Fixed bugs in response interpolation for low energies
• Changed gauss smoothing function call to take absolute FWHMs. Anything else is just unexpected an confusing, I think
• Finished the compton subtraciton examples: How good is the match? -> Get impressions from Magne and Ann-Cecilie

fzeiser included the following code: https://github.com/oslocyclotronlab/ompy/pull/38/commits

@magneg and @cecgresonant: Can we discuss whether this is good/good enough/better/worse then the results obtained from mama?

Have a look at the pictures at the very last cell in https://github.com/oslocyclotronlab/ompy/blob/dev/compton/notebooks/code_testing/Test%20compton%20subtraction%20method.ipynb

• [x] check that folding & unfolding of a spectrum works "reversible"
• [ ] Compare how many iterations are selected in mama
• [ ] add a hook to stop after iteration X (now, I think the "best" iteration in is selected)
• [x] update Documentation on the above point (# interations vs. max. #iterations)

• Decided that we will not implement the "stop after x iterations" hook. Plots can be obtained from the "plot_hooks" hook.
• Results from mama quite similar, but have a look at the very lowest Ex bin!
