CalcChi2()

void FitRTDist::CalcChi2 ( const double *  pars, double &  chi2, int &  ndf  )

static

N of parameters = m_n_pt + 1 pars[0] = T1 [1] = T0 [2] = DR (constant over T) [3]...[m_n_pt] = R at each non-edge T points

Note that the T position of each point is not fixed but depends on T1 & T0.
