isobarDecayTopology: Fix wrong isospin symmetrization with > 1 group #144

Closed stefan-wallner closed 8 years ago

stefan-wallner commented 8 years ago

Partial waves with more than one isospin group (e.g. K- pi- pi+) lead to too much isospin terms in the isospin symmetrization due to a wrong handling of groups.

legordian commented 8 years ago

A general question: Did you verify that your code gives the same results for all 5\pi topologies?

stefan-wallner commented 8 years ago

Fixed further formatting issues. I performed a quick test with one of your ( @legordian ) amplitudes to see if isospin systematization is applied. A quick test with your PWA would be great.

Successfully tested on a 5pi sample and merged. Thank you!
