ROOTPWA is a toolkit for partial-wave analysis of multi-particle final states produced in high-energy particle reactions. It is used to determine hadron spectra from experimental data.
The arguments of the fitResult::intensity method are regular expressions for wave names, the arguments of the fitResult::intensityErr method are regular expressions for production amplitudes. Usually this is not a big problem, but if one requires that the pattern has to match from the beginning of the wave name (i.e. it starts with the ^ character), then intensityErr will not return a valid result. This should somehow be improved.
It seems that at the moment it is not possible to obtain the intensity in one particular rank (but only the sum over all ranks), so probably the way out is to use a pattern for the production amplitudes also in fitResult::intensity.
