template<class T> std::vector<T> fastjet::objects_sorted_by_values (  const std::vector< T > &  objects, const std::vector< double > &  values )

given a vector of values with a one-to-one correspondence with the vector of objects, sort objects into an order such that the associated values would be in increasing order (but don't actually touch the values vector in the process).

void fastjet::sort_indices (  std::vector< int > &  indices, const std::vector< double > &  values )

sort the indices so that values[indices[0->n-1]] is sorted into increasing order

std::vector<PseudoJet> fastjet::sorted_by_E (  const std::vector< PseudoJet > &  jets  )

return a vector of jets sorted into decreasing energy

std::vector<PseudoJet> fastjet::sorted_by_pt (  const std::vector< PseudoJet > &  jets  )

return a vector of jets sorted into decreasing transverse momentum

std::vector<PseudoJet> fastjet::sorted_by_rapidity (  const std::vector< PseudoJet > &  jets  )

return a vector of jets sorted into increasing rapidity

Variable Documentation

const double fastjet::MaxRap = 1e5

Used to protect against parton-level events where pt can be zero for some partons, giving rapidity=infinity. KtJet fails in those cases. Definition at line 50 of file PseudoJet.hh. Referenced by fastjet::PseudoJet::_finish_init().
