Orsay: detector configurations AGAIN

I finally got wise and did the high-school geometry necessary to describe the positions of the edges of detectors. Here's what the Deep Space 9 ordinary positions look like...



...and here's my current favourite configuration, affectionately known as "configuration 5"...



For both of these, the legend gives the relevant position information: r, theta and phi values for the centre of each detector.

Here's the hit patterns for elastic scattering (using a Rutherford-esque cross section)...





...and the hit patterns for the reaction...
