Dear all,

could you please suggest what is the best way to reconstruct electrons in pandaroot-mar15? and how can one apply Bremsstrahlung corrections?
Is there an example macro, on the wiki page or somewhere?

Let's start from the simple case:

theAnalysis->FillList(eplus, "ElectronAllPlus");
theAnalysis->FillList(eminus, "ElectronAllMinus");

Like so, of course one gets a big left tail. How to proceed, then?

Thanks in advance for your useful help and courtesy,

Elisabetta

Hi Elisabetta,

I think you just (in full sim only available) request

theAnalysis->FillList(eplus, "ElectronBremAllPlus");
theAnalysis->FillList(eminus, "ElectronBremAllMinus");

instead. Done.

Best,
Klaus

Hello Klaus,

thanks for the info. Then, a good electron list exists and we can use it.

My best, Elisabetta

Hello.
Can anyone point me to / provide me with plots showing the effect of the bremsstrahlung correction method?
Thanks.
