示例1: get_contour
TNtuple* LikelihoodSpace::get_contour(float delta) {
TNtuple* contour = (TNtuple*) this->samples->Clone("lscontour");
contour->Reset();
// Get list of branch names
std::vector<std::string> names;
for (int i=0; i<this->samples->GetListOfBranches()->GetEntries(); i++) {
std::string name = this->samples->GetListOfBranches()->At(i)->GetName();
if (name == "likelihood") {
continue;
}
names.push_back(name);
}
float* params_branch = new float[names.size()];
for (size_t i=0; i<names.size(); i++) {
this->samples->SetBranchAddress(names[i].c_str(), ¶ms_branch[i]);
}
float ml_branch;
this->samples->SetBranchAddress("likelihood", &ml_branch);
// Build a new TNtuple with samples inside the contour
float* v = new float[names.size() + 1];
for (int i=0; i<this->samples->GetEntries(); i++) {
this->samples->GetEntry(i);
if (ml_branch < this->ml + delta) {
for (size_t j=0; j<names.size(); j++) {
v[j] = params_branch[j];
}

contour->Fill(v);
}
}

delete[] v;
