Hi Koay this is the OPAL results for the 1mA Gauss with one sigma cutoff:

Dist:DISTRIBUTION, TYPE=gauss,

                   INPUTMOUNITS=NONE,

                   sigmax= 1e-03, sigmapx=gambet*10e-3, corrx=0.0,
CUTOFFX=1,

                   sigmay=1e-3, sigmapy=gambet*10e-3, corry=0.0,  
CUTOFFY=1,

                   sigmaz= 0.1e-3, sigmapz=gambet*5e-3, corrz=0.0,
CUTOFFLONG=1;

This is the an analytic solution, cold beam with linear space charge for an unifirm distribution:

The Mathematica notebook is attached.

I think this proves that the OPAL results are reasonable close.
