std::vector< art::Ptr< recob::Hit > > dune_ana::DUNEAnaHitUtils::GetHitsOnPlane ( const std::vector< art::Ptr< recob::Hit >> &  hits, const geo::PlaneID::PlaneID_t  planeID  )

static

Get all hits on a specific plane.

Parameters

hits	the hit vector to be searched for hits on a specific plane
planeID	the requested plane number

Returns

the hit vector containing hits on a specific plane

Definition at line 31 of file DUNEAnaHitUtils.cxx.

    std::vector<art::Ptr<recob::Hit>> hitsOnPlane;
    std::vector<art::Ptr<recob::Hit>>::const_iterator hitIt = hits.begin();
    while ((hitIt 
        = std::find_if(hitIt, hits.end(), [planeID](const art::Ptr<recob::Hit> &hit){return hit->WireID().Plane==planeID; }))

std::vector< art::Ptr< recob::SpacePoint > > dune_ana::DUNEAnaHitUtils::GetSpacePoints ( const art::Ptr< recob::Hit > &  pHit, const art::Event &  evt, const std::string &  hitLabel, const std::string &  hitToSpacePointLabel  )

static

Get the space points associated with the hit.

Parameters

pHit	is the spacepoint for which we want the hits
evt	is the underlying art event
hitLabel	is the label for the hit producer
hitToSpacePointLabel	is the label for the association between hit and space point

Returns

vector of art::Ptrs to the hits

double dune_ana::DUNEAnaHitUtils::LifetimeCorrectedTotalHitCharge ( detinfo::DetectorClocksData const &  clockData, detinfo::DetectorPropertiesData const &  detProp, const std::vector< art::Ptr< recob::Hit > > &  hits  )

static

get the total hit charge, corrected for lifetime

Parameters

hits	the vector of hits to be summed over

Returns

the lifetime corrected total hit charge

Definition at line 65 of file DUNEAnaHitUtils.cxx.

{
    double totalHitCharge(0);
    for (unsigned int iHit = 0; iHit < hits.size(); iHit++)
        totalHitCharge += hits[iHit]->Integral() * DUNEAnaHitUtils::LifetimeCorrection(clockData, detProp, hits[iHit]);

    return totalHitCharge;
}

double dune_ana::DUNEAnaHitUtils::LifetimeCorrection ( detinfo::DetectorClocksData const &  clockData, detinfo::DetectorPropertiesData const &  detProp, const art::Ptr< recob::Hit > &  pHit  )

static

get the lifetime correction for a hit, assumes the detector properties GetTriggerOffset is T0

Parameters

phit	is the hit

Returns

the charge normalisation correction

Definition at line 44 of file DUNEAnaHitUtils.cxx.

{
    return DUNEAnaHitUtils::LifetimeCorrection(clockData, detProp,
                                               pHit->PeakTime(), clockData.TriggerTime());
}

double dune_ana::DUNEAnaHitUtils::LifetimeCorrection ( detinfo::DetectorClocksData const &  clockData, detinfo::DetectorPropertiesData const &  detProp, const double  timeInTicks, const double  t0InMicroS  )

static

get the lifetime correction for a particular time

Parameters

timeinTicks	the time in ticks
t0InMicroS	the t0 time in micro seconds

Returns

the charge normalisation correction

Definition at line 52 of file DUNEAnaHitUtils.cxx.

{
    const double tpcSamplingRateInMicroS(clockData.TPCClock().TickPeriod());
    const double tpcTriggerOffsetInTicks(trigger_offset(clockData));

    const double timeCorrectedForT0((timeInTicks - tpcTriggerOffsetInTicks)*tpcSamplingRateInMicroS - t0InMicroS);
    const double tauLifetime(detProp.ElectronLifetime());

    return std::exp(timeCorrectedForT0/tauLifetime);
}
