Detailed Description

Finds and applies trigger prescales on Single Photon data.

The names of the triggers used, prescales and thresholds are located in the config file.

Performs also a cleaning based on the reconstructed photon pT: if the event does not fire the trigger with the pT threshold just below the photon pT, the event is rejected. This cleaning is performed both on data and MC, while the prescales are applied only on data.

Member Function Documentation

int PhotonPrescales::GetPhotonPrescale

(

double

photonPt

)

const

Gets the prescale for a given run and lumi, from the prescale map.

If the event is from a MC file, the function will only return 0 or 1.

Returns 0 if the event fails the check based on the trigger threshold.

Parameters:

[in]	photonPt	p_T of the (first) photon in the event.
[in]	run	the run number of the event
[in]	lumi	the luminosity block of the event

std::vector<double> PhotonPrescales::GetThresholdsBinning

(

)

const

Gets vector of pT thresholds bin boundaries for the weights histograms.

By construction, first bin starts at 0 and last bin ends at 1500 GeV (unless the last threshold is above 1500).

static std::vector<PhotonTrigger> PhotonPrescales::GetTriggers	(	Dataset &	dataset,
		Options const &	options
	)			[static, private]

Gets the triggers from the config file.

Also orders the triggers by increasing pT thresholds (mandatory for GetWeight).
