Online vs. Offline
Offline analysis will want to validate SVT trigger, compute efficiencies etc. Exact information of SVT configuration at the time data were taken must be available.
There may be drawback. E.g. would prevent dynamical adjustment for beam movement by <d> subtraction to smooth out small oscillations on the minute time scale.
SVT geometry must be made to relate with offline one. Not an understood problem yet. What if two beam monitor program report differently?
