Hi,

I just run it (QAmacro_emc_x.C) with 10000 events and there is really a significant shift in phi... well, at least on my computer. Let me attach figures which shows it: the difference between phi(cluster)-phi(MC) versus the phi angle (!) of the photon (histogram h2phi in the macro)...

index.php?t=getfile&id=5757&private=0

Alternatively, the difference against the polar angle... it appears to be related to the barrel part...

index.php?t=getfile&id=5758&private=0

Greetings,

Johan
