/*
 *  File: DataFormats/Scalers/interface/L1AcceptBunchCrossing.h   (W.Badgett)
 *
 *  Bunch crossing information for a single L1 accept.  The information 
 *  comes from the Scalers FED.   Normally there are four of these objects 
 *  per event, each representing the current L1 accept, as well as the 
 *  previous three L1 accepts in time.
 *
 *  orbitNumber_     32-bits     Orbit counter since last reset
 *  bunchCrossing_   0...3563    Bunch counter within orbit
 *  eventType_       0...7       Event Type: 
 *                               1: Physics
 *                               2: Calibration
 *                               3: Test
 *                               4: Technical
 *  l1AcceptOffset_              Offset of the L1 Accept relative to 
 *                               the current event's L1 accept
 *                               Typically 0, -1, -2, -3
