Trigger and Readout

Prescale Records Every Nth Accepted Event

Prescale readout and the source ledger close the chain. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

A prescale records every third accepted event

There are 12 accepted events and a prescale of 3.

Nrecorded=12/3N_{\text{recorded}}=12/3

Four events are recorded

The exact recorded count is 4.

The reconstruction ledger cites each source

The audit keeps 5 checked source roles: coverage, occupancy, centroid, trigger, and recorded events.
