fitResult::intensityErr(const std::string&) broken for non-rank-1 fits #140
// get amplitudes that correspond to wave name pattern
const vector<unsigned int> prodAmpIndices = prodAmpIndicesMatchingPattern(waveNamePattern);
const unsigned int nmbAmps = prodAmpIndices.size();
if (not _covMatrixValid or (nmbAmps == 0)) {
return 0.;
}
if(nmbAmps == 1) {
return intensityErr(prodAmpIndices[0]);
}
This will get the indices to the production amplitudes based on the pattern specified, and if only one production amplitude is found, call intensityErr with the corresponding index. However, intensityErr takes wave indices. The indices for production amplitudes and waves are different for anything but rank-1 fits. Symptoms might vary from a wrong value to crashes/exceptions.
