Detailed Description

Find the size of the cluster in phi using L2 cells.

Parameters

cp0	the reference position in calo-coordinates
cluster	the cluster filled with L2 and L3 cells

The window is computed using only cells in the second layer. Asymmetric sizes are computed for barrel and endcap. The size is the maximum difference in phi between the center of a cell and the refence, considering separately cells in the barrel and in the endcap. The computation is done separately for the cells with phi < reference phi or >=. A cutoff value of 1 is used.
