利用本视频rf205_compplot.C程序中定义的sig1,sig2,bkg1,bkg2进行画图，与model.plotOn(xframe,Components(RooArgSet(“bkg1,sig1,sig2”)))所得结果不等效的是： A、 model.plotOn(xframe,Components(RooArgSet(“bkg1,si*”))); B、 model.plotOn(xframe,Components(RooArgSet(bkg1,sig*))); C、 model.plotOn(xframe,Components(RooArgSet(“bkg1,s*”))); D、 model.plotOn(xframe,Components(RooArgSet(bkg1,sig1,sig2)));
