29// MHThetaSqN
30//
31// For more detailes see MHAlpha.
32//
33// How to use this class:
34// - in your ganymed.rc add:
35// MJCut.NameHist: MHThetaSqN
36// - setup the number of off-source regions in your ganymed.rc by:
37// MHThetaSqN.NumOffSourcePos: 2
38// - switch on/off whether an off-theta cut should be done:
39// MHThetaSqN.DoOffCut: Yes,No
40// - and if necessary switch off the Theta cut in your Magic cuts:
41// Cut1.ThetaCut: None
42//
