TVector3 EEmcGeomSimple::getDirection	(	const Float_t	detaBin,
		const Float_t	dphiBin
	)		const

gets 'direction' vector from (0,0,0) toward a point on EEMC. detaBin is defined from [-0.5,11.5). [-0.5,0.5) returns a point within etabin 1, [0.5,1.5) within etabin 2, etc... dphiBin is defined similarly.

Parameters

detaBin	[-0.5,11.5)
dphiBin	[-0.5,59.5)

Returns: direction as TVector3
