The integrated rates on the upstream counters have to be in the range 0-15 Hz (rates up 100 Hz are acceptable) and the rates on the midstream counters have to be in the range 10-20 Hz (acceptable up to 50 Hz) @50 nA. Counting rates in the range of hundreds of Hz may indicate bad beam tune or bleed-through from other Halls.
