CbmRichRingSelectAnn Class Reference

Implementation for concrete RICH ring selection algorithm: reject rings using a trained neural net (input file with weights needed!) store resulting value (0-1) in "SelectionNN": 0 = good rings 1 = rings to be rejected --> choose a value in between depending on required purity/ efficiency. More...
