Detailed Description

Class to do the sharing correction for MC data.

Input:

• AliESDFMD object - from reconstruction
• Kinematics
• Track-References

Output:

• AliESDFMD object - copy of input, but with signals merged

Corrections used:

• None

Histograms:

• For each ring (FMD1i, FMD2i, FMD2o, FMD3i, FMD3o) the distribution of signals before and after the filter.
• For each ring (see above), an array of distributions of number of hit strips for each vertex bin (if enabled - see SetupForData method)
