Detailed Description

Aligning the clocks of independent digitiser boards.

Boards free-run on their own clocks, so hits from one board carry a constant offset against another's. Events cannot be built across boards until that offset is measured and removed.

The beam method measures it from the data itself: the beam's own time structure appears on every board, so the shift that best superimposes one board's structure on the reference board's is the offset between them.
