Detailed Description

Auxiliary class to determine time of DAQ objects.

The time is relative to the fixed time defined in JDAQUTCExtended.
For DAQ events, the time is offset by the product of the event counter and a constant weight.
To correlate DAQ events with summary data, the weight should be set to a value such that this product is strictly less than half of the frame duration.

Member Function Documentation

double KM3NETDAQ::JDAQEvaluator::operator() ( const JDAQUTCExtended &  object ) const

inline

Get time of object.

Parameters

object

UTC time

Returns

time [s]

Definition at line 37 of file JDAQEvaluator.hh.

    {
      return getTimeDifference(JDAQUTCExtended::getInstance(), object);
    }

double KM3NETDAQ::JDAQEvaluator::operator() ( const JDAQHeader &  object ) const

inline

Get time of object.

Parameters

object

DAQ header

Returns

time [s]

Definition at line 49 of file JDAQEvaluator.hh.

    {
      return(*this)(object.getTimesliceStart());
    }

double KM3NETDAQ::JDAQEvaluator::operator() ( const JDAQEventHeader &  object ) const

inline

Get time of event.

Parameters

object

event header

Returns

time [s]

Definition at line 61 of file JDAQEvaluator.hh.

    {
      return getTimeDifference(JDAQUTCExtended::getInstance(), object.getTimesliceStart())  +  object.getCounter() * getWeight();
    }

static double KM3NETDAQ::JDAQEvaluator::getWeight ( )

inlinestatic

Get relative weight for JDAQEventHeader evaluation.

This value should be less than half of the frame duration in units of seconds divided by the expected maximum number of events in a single data taking run.

Returns

weigth [s]

Definition at line 75 of file JDAQEvaluator.hh.

    {
      return 1.0e-7; // [s]
    }
