Member Function Documentation

bool JCALIBRATE::JPairwiseComparator::operator() ( const pair_type &  first, const pair_type &  second  ) const

inline

Comparison of two pairs of PMT addresses.

Parameters

first	first pair of PMT addresses
second	second pair of PMT addresses

Returns

true if first pair has larger space angle; else false

Definition at line 68 of file JCalibrateK40.hh.

    {
      using namespace std;

      if      (fabs(this->getDot(first) - this->getDot(second)) > epsilon)
        return this->getDot(first) < this->getDot(second);
      else if (max(first.first, first.second) == max(second.first, second.second))
        return min(first.first, first.second) < min(second.first, second.second);
      else
        return max(first.first, first.second) < max(second.first, second.second);
    }

double JCALIBRATE::JPairwiseComparator::getDot ( const pair_type &  pair ) const

inline

Get cosine of space angle between PMT axes.

Parameters

pair	pair of PMT addresses

Returns

cosine

    {
      return JMATH::getDot(module.getPMT(pair.first) .getDirection(),
                           module.getPMT(pair.second).getDirection());
