=========================================
 This is EKHARA, version 2.3
 Process:                e+e- -> e+e-eta
 The cross section will be calculated
 Matrix element: 
                |M_t|^2
 Estimating UpperBound with [    0.100E+05 ] iterations...                     
  
 Wait for [    0.140E-40 ] events to be accepted..                             
  
  MC efficiency (evt/eff.iter)  =     0.000E+00                                
  
 ================================
 From all weights
  Integral Cross Section =  2.34456D-09 +-  1.24D-11 [GeV^-2]                  
                         =  9.12922D-04 +-  4.82D-06 [nb]

 ================================
 From UNWEIGHTED events
  Integral Cross Section =  2.34289D-09 +-  2.29D-11 [GeV^-2]                  
                         =  9.12271D-04 +-  8.92D-06 [nb]
