SVT monitoring
Will likely need 2 monitor programs:
- one standard consumer runs off the Level3 data to validate SVT triggers (make sure when we say impact parameter is high, it really is. Do not waste trigger bandwidth on fakes)
- let’s not worry about this one now
- one special SVT Spy Buffer monitor program (SVT monitor) looks at events rejected by SVT to make sure they really had to get lost.SVT reduction is O(103), and these events do not make it past Level 2 in other ways… for each event we see in Level 3, there are 999 we will never see. Make sure efficiency is under control.
- Spy Buffers keep history of all data processed by SVT
- Spy Buffers are read from VME without interfering with trigger processing.
- Spy Buffers are the favorite place for SVT monitor
