Constructor & Destructor Documentation

EpFinder::EpFinder	(	int	nEventTypeBins = `10`,
		char const *	OutFileName = `"EpFinderCorrectionHistograms_OUTPUT.root"`,
		char const *	CorrectionFileName = `"EpFinderCorrectionHistograms_INPUT.root"`,
		int	pbinsx = `1`,
		int	pbinsy = `1`
	)

Constructor. Initializes values and reads correction file, if it exists. This file is actually PRODUCED by the code in an earlier run. The user must rename the file EpFinderCorrectionHistograms_OUTPUT.root if he wants to use it.

Parameters

CorrectionFileName	Full name of the .root file with correction histograms.
nEventTypeBins	Number of EventType bins that the user is using. Up to the user to have a consistent usage, here and in analysis.
pbinsx,pbinsy	Number of detector index bins for phi correction

Member Function Documentation

void EpFinder::Finish ( )

call this method at the end of your run to output correction histograms to a file (you can choose to use these or not) and to calculate EP resolutions

TString EpFinder::Report ( )

Returns a big string that tells in text what the settings were. This is for your convenience and is of course optional. I like to put a concatenation of such Reports into a text file, so I "autodocument" what were the settings for a given run

Here is the caller graph for this function:

EpInfo EpFinder::Results	(	std::vector< EpHit > *	EpdHits,
		int	EventTypeID
	)

returns all information about the EP. A large object of type StEpdEpInfo is returned, so you don't have to call the EpFinder over and over again for various information

Parameters

EpdHits	Epd Hits in a TClones array. Will be decoded as StEpdHit, StMuEpdHit, or StPicoEpdHit as dictated by mFormatUsed
primVertex	primary vertex position for this event
EventTypeID	user-defined integer specifying EventType of the event. User must use same convention in correction histograms and weights

note the "+1" since EventTypeId begins at zero

void EpFinder::SetMaxTileWeight ( double MAX )

inline

sets the maximum weight, in units of nMIP, for determining tile weights TileWeight = (EpdHit->nMIP()>thresh)?((EpdHit->nMIP()>MAX)?MAX:EpdHit->nMIP()):0;

Parameters

MAX	maximum tile weight. If epdHit->nMIP()>MAX then weight=MAX

sets the threshold, in units of nMIP, for determining tile weights TileWeight = (EpdHit->nMIP()>thresh)?((EpdHit->nMIP()>MAX)?MAX:EpdHit->nMIP()):0;

Parameters

thresh threshold. If epdHit->nMIP() is less than thresh, then weight is zero
