		Double_t	y,
		Double_t	z,
		Char_t &	ring,
		UShort_t &	sector,
		UShort_t &	strip
	)		const

Translate spatial coordinates (x,y,z) in the master reference frame of ALICE to the detector coordinates (detector, ring, sector, strip). Note, that if this method is to be used in reconstruction or the like, then the input z-coordinate should be corrected for the events interactions points z-coordinate, like

geom->XYZ2Detector(x,y,z-ipz,d,r,s,t);

Parameters
