Dear all,

Please find attached the inbending and outbending comparison for the 
electron and proton xyz vertex and their differences. The only 
significant difference I can see between ccdb and sqlite, is a shift in 
the outbending Vy sqlite distribution away from 0, both for electron and 
proton.

Best,

Samy
