Detailed Description

Concrete implementation of a DTTTrigBaseSync. This class define the offset for RecHit building of data and simulation. The offset is computes as:
offset = t0 + tTrig + wirePropCorr - tofCorr
where:

• t0 from test pulses (taken from DB, it is assumed to be in ns; can be switched off)
• ttrig from the fit of time boxrising edge (taken from DB, it is assumed to be in ns) (At the moment a single value is read for ttrig offset but this may change in the future)
• signal propagation along the wire (can be switched off): it is assumed the ttrig accounts on average for correction from the center of the wire to the frontend. Here we just have to correct for the distance of the hit from the wire center.
• TOF correction (can be switched off for cosmics): the ttrig already accounts for average TOF correction, depending on the granularity used for the ttrig computation we just have to correct for the TOF from the center of the chamber, SL, layer or wire to the hit position. NOTE: particles are assumed as coming from the IP.

The emulatorOffset is computed as:
offset = int(ttrig/BXspace)*BXspace + t0
where:

• t0 from test pulses (taken from DB, it is assumed to be in ns; can be switched off)
• ttrig from the fit of time box rising edge (taken from DB, it is assumed to be in ns)
• BXspace BX spacing (in ns). Can be configured.

NOTE: this should approximate what is seen online by the BTI

Member Function Documentation

double DTTTrigSyncFromDB::emulatorOffset ( const DTWireId &  wireId, double &  tTrig, double &  t0cell  )

virtual

Time (ns) to be subtracted to the digi time for emulation purposes It does not take into account TOF and signal propagation along the wire It also returns the different contributions separately:

• tTrig is the offset (t_trig)
• t0cell is the t0 from pulses
