Function Documentation

Long64_t BuildTree	(	const std::string &	inputFileName,
		const std::string &	outputDirName,
		const Long64_t	maxEvent,
		const std::string &	logFileName
	)

This is an example function to generate ROOT files. It can be used "out of the box". If more control over the output is desired, then the settings of the Forester can be tweaked to do so.

double computeHermesPhiH	(	const TLorentzVector &	hadronInPrf,
		const TLorentzVector &	leptonInPrf,
		const TLorentzVector &	photonInPrf
	)

Calculate the hadron azimuthal angle around the virtual photon direction with respect to the lepton scattering plane in the proton rest frame. We use the HERMES convention, returning an angle in the range [0,2pi]. The vectors passed as arguments should already be boosted to the proton rest frame. Incident and scattered leptons, incident protons and virtual photons all return -999.

char getFirstNonBlank

(

const std::string &

line

)

Returns the first non-blank character in a line. Returns \0 if there are no non-blank characters in the line.

This function converts our tree format to HepMC3 It would be better to skip the ROOT step, but that would require a lot of duplication and/or refactorization
