Detailed Description

Utility class to determine if a chain should be prescaled/passed-through using its PS/PT factor, implemented with a periodic algorithm (take every [factor] event).

Utility class to determine if a chain should be prescaled/passed-through using its PS/PT factor, implemented with a periodic algorithm (take every [factor] event and always 1st event)
