Dear Zisis,

thanks for the quick answer. I think a report on the status quo would be a
good thing, because it will help to discuss how to improve things. Mihajlo
if you are ready to present your findings on the bcal photon
reconstruction, absolutely perfect and more than welcome.

I have reserved a room with a standard jlab polycom system for both days,
so things should work, nicer than with my DESY (!) laptop.

cheers elke
