4 // you use for your detector in the SetDefaultParameters() method here
5 // The place to do this is marked by //implement your own here//
6 // The parameters have no units, they need to be converted in the
7 // AllSi_Al_support_Detector::ConstructMe() method
8 // but the convention is as mentioned cm and deg
