Registration (12:00 ->12:45 )  

Lunch (12:45 ->13:30 )  

Status of em Scale (13:30 ->14:50 )
The idea is to review how we arrive at the em scale for the various sub-calo\'s. What are the limitations, what has to be done in situ? We assume that the \'raw signal reconstruction\' as obtained from calibration (ramps and optimal filtering) is understood.
