sorry, I am somwewhat confused, from the following code I thought that the max_threshold is actually in the dimension of the second dimension:

```
  std::vector<std::pair<double, double> > MRMRTNormalizer::llsm_rss_inliers(
      std::vector<std::pair<double, double> >& pairs,
      std::pair<double, double >& coefficients, double max_threshold) 
  {
    std::vector<std::pair<double, double> > alsoinliers;
  
    for (std::vector<std::pair<double, double> >::iterator it = pairs.begin(); it != pairs.end(); ++it)
    {
      if (std::fabs(it->second - (coefficients.first + ( coefficients.second * it->first))) < max_threshold) 
      {
        alsoinliers.push_back(*it);
      }
    }
  
    return alsoinliers;
  }

```

so the second dimension would be iRT, right?
