void AnitaEventFaker::addSignal	(	UsefulAnitaEvent *	event,
		double	theta_deg,
		double	phi_deg,
		double	A = 10,
		double	extra_delay = 0,
		std::complex< double >	jones_H = std::complex<double>(1,0),
		std::complex< double >	jones_V = std::complex<double>(0,0)
	)		const

Add a signal to this event coming from that direction

Parameters

event	the event to add the signal to
theta_deg	the degrees theta (with positive coming from below) for the signal , in payload coordinates
phi_deg	the degrees phi of the signal , in payload coordinates
A	a scale factor for the signal
jones_H	complex Jones H-pol coefficient
jones_V	complex Jones V-pol coefficient

const TF1 & AnitaEventFaker::getDefaultMagResponse ( )

static

Retrieves the default magnitude response used.

Definition at line 32 of file AnitaEventFaker.cc.

const AnalysisWaveform& AnitaEventFaker::getSignal ( int  ant, int  pol  ) const

inline

Return the current realization of the signal. This is the prottype convolved with each response

Definition at line 78 of file AnitaEventFaker.h.

UsefulAnitaEvent * AnitaEventFaker::makePureNoiseEvent	(	double	rms = 0.1,
		UsefulAnitaEvent *	victim = 0
	)		const

This is just a helper function to make a pure noise event, where each channel is populated with random noise

Parameters

rms	The RMS of the noise, in pre-response units
victim	If non-zero, this event will be filled with noise instead of constructing a new event.

void AnitaEventFaker::setSignal

(

const AnalysisWaveform &

sig

)

This explicitly sets the signal Note that the power will be rescaled to one.

Definition at line 58 of file AnitaEventFaker.cc.

void AnitaEventFaker::setSignalFromMagnitudeResponse	(	const TF1 &	mag_response,
		double	delay = 30,
		double	signal_dt = 5e-2,
		int	npoints = 2000
	)

These generates the signal based on the minimum phase signal corresponding to the specified magnitude response. The signal will be convolved with the impulse response.

Parameters

mag_response	a function giving the magnitude response (in relative units, as the power will be scaled away )
delay	the delay to apply to the signal (should be about the trigger delay)
signal_dt	the level to interpoalte the signal too. it will then be linearly interpolated on top of the event, so this should be significantly smaller than the sampling period of the events
