background removed calibration : 1- XAS energy reference from standard similar LSMO (maximum of MnL3 peak) 2- energy dispersion calibration of the detector from two peaks reference in low and core loss areas (STO substrate area in the multimayer system). see also TiL3 Analyst: imhoff. Temperature: Room.
