Detailed Description

XANADOO class for Et Miss. Total (Ecal+Hcal) EtMiss is calculated using algorithms specified for ConcreteMet objects ( see JetMetAnalysis/MetBuilers ). This value can be set via EtMissScheme variable in .orcarc file.

Missing Et is computed for ECAL and HACL always summing the Et in all the cell of ECAL and HCAL separately. Also the energy deposition (scalar sum of energy in the cells) in the two calorimeters is calculated. It is possible to set a threshold on Et of cells entering the sum.

Note: in get Methods (int i) for "vectorial" quantities i=0,1,2 return x,y,z values for the quantity; i=3 returns transverse Et ( sqrt(x^2+y^2) ) i=4 retrns modulus of E ( sqrt(x^2+y^2+z^2) )

for scalar quantities i=0,1,2 return x,y,z values for the quantity; i=3 returns the sum of transverse Et ( sqrt(x^2+y^2) ) in each cell i=4 returns the sum of modulus of E ( sqrt(x^2+y^2+z^2) ) in each cell

Note: The values returned are the energy deposited in the detector, so the missing Et components are just the opposite of that. THe methods getEMissX(),getEMissX(),getEtMiss() return already the right quantities.
