Hi,


in order to MC match decays with additional photons from PHOTOS, I added some functionality to PndAnalysis which can be used with

PndAnalysis::McMatchAllowPhotos(int maxn=1, double thresh=0.05)

It takes as parameters the allowed maximum number of missing photons maxn (per decay node!), which all have to have an energy E<thresh.

This is still kind of experimental, so please let me know any problems or buggy behaviour you observe. Up to now I only tested the feature with FastSim. Since photons coming from PHOTOS are indistinguishable from primary ones, I don't see a better filtering possibility.


Best,
Klaus
