@stefanv I'd like to pair each chapter with some real data. Any ideas for where to use this snippet?

I also would like to find a snippet that uses scipy.optimize.

A registration example could include real data + optimization. We could also ping @matthew-brett for ideas; he recently taught a class on this topic.

I'm sure loads of people have examples of fitting peaks. My own research fitted peaks on atomic-resolution images of crystals, and used the fit parameters to say things about the crystal imperfections. This was 2D fitting, which you could expand the example to reasonably easily. I don't do much microscopy myself these days, but could connect you with some good friends at SuperSTEM if that sounds like the kind of data set you might want.
