L1CaloEtScale::L1CaloEtScale	(	const double	linearLsbInGeV,
		const std::vector< double > &	thresholdsInGeV
	)

ctor that provides backwards compatibility with fixed scale max values OK to use this with e/gamma and jet rank scales

		const unsigned	rankScaleMax,
		const double	linearLsbInGeV,
		const std::vector< double > &	thresholdsInGeV
