Hi,

to get my charged candidates filled, I did now a workaround for PndMicroWriter.cxx in /PndTools/AnalysisTools.
Its just a simple workaround, which gives me the 4 vectors and charge of charged candidates in tcands.root.

But there are still informations about the covariant matrix missing. So I can't do a vertex fit in my analysis.

I also got a fist spectrum with 100 events, which I have enclosed.
The first is the gamma spectrum (top, left), which has a lot of background. Pions are there, but the peak is not very clear. I guess that there are also hits from charged particles in the EMC, which are filled in the gamma list. Is this possible?
And how can I get rid of the background?

Bernhard
