Error Handling
Years long debate. We now have a final agreement.
Two kind of errors:
- SVT_Error for internal use. Details spared.
- CDF_Error for error that requires full DAQ re-sync
- one month ago: SVT does not pull CDF_Error, just passes error flags to Level2 in the data stream
- now: each SVT board will pull CDF_Error as soon as it detects a severe error condition (if it can)
